this to build for NetBSD/powerpc:
* need a cast in one place (in the renamed patch)
* an overcautious assert() is incompatible with top/down VM layout in NetBSD
This still doesn't work on NetBSD/powerpc, though, and I ran out of time.
The build produces a mono-boehm.core file the first time through the build
(for some reason not the subsequent attempts, sigh!), and I have problems
reconstructing the CLI to run the mono-boehm executable under gdb, and the
core file says it got a segv in opendir() which must be nonsensical.

Mono 4.0.2 Release Notes
Release date: 30 Jun 2015
4.0.2 is the second maintenance release of the 4.0 series
Improvements
XBuild fixes (MonoDevelop no longer fails to build if Gtk#3 is installed)
Bug Fixes
29639: Moq related Nunit tests fail with RemoteException (Unix transport error) since Mono 4.0
29898: Bump Mono NuGet to 2.8.5
29935: XAttribute.ToString() outputs wrong result if attribute contains namespace
(1) Default heap limit to 75% of available address space.
(2) Limit GC marker threads to 4MB/8MB (32bit vs 64bit) stack space.
As Mono tries to create 16 such threads by default, the default
stack size on AMD64 would eat 2GB VA alone.
Bump revision.
Also: general patch refresh
Upstream release notes:
Mono 3.10.0 is a bugfix release with a few features.
Highlights
Implemented System.IO.Compression.FileSystem.
Uri now implements the .NET 4.5 behavior, it can be reverted to
the old behavior in the same way by setting the System.Uri::s_IriParsing
static field to false.
Performance
Remove unnecessary locking from core metadata parsing functions.
Avoid cache thrashing of locals array when looping over enumerator.
Known Issues
The OSX packages have an invalid libgdiplus library that affects
users of System.Drawing that requires it to work.
This specially affects Xamarin.Mac users that fit the following criteria:
Uses Xamarin.Mac Classic (Unified is unaffected).
Uses the subsets of System.Drawing that use libgdiplus.dylib internally
- System.Drawing.RectangleF, PointF, Colors are unaffected
- System.Drawing.Bitmap, and font for example are affected
The symptom of the problem is your application failing with:
“System.TypeInitializationException: An exception was thrown by
the type initializer for
System.Drawing.GDIPlus —> System.Exception: GdiplusStartup”

------------------------------------------------------------------------
Mono 3.8.0 has 711 commits since the last release.
This is the work of 61 contributors since May 28. 58 bugs were fixed.
Highlights
Major performance and scalability improvements across the the whole runtime.
Finished the Windows 64 port.
Debugger wire protocol optimized for usb connections.
Debugger
Updated wire protocol better handles high latency connections such
as those found when doing USB debugging.
Client library now aggressively caches information and batches
requests. Under one test scenario single stepping packets
transmitted dropped from 2233 to only 16, with the latency going
from seconds to 20 milliseconds.
Performance
The JIT now better handles long remainders by powers of two,
generating significantly better code.
Over 10x faster code is generated for delegates that are only
invoked once. C# features such as async and LINQ produce a lot of
those delegates, so this improvement will impact everyone.
Improved alias analysis can now handle second order aliases and
eliminate null checks.
The runtime now has a concurrently readable hashtable that can
makes reflection heavy workloads significantly faster and more scalable.
Garbage Collection
Optimized one of the core data structures of the garbage collector;
should result in 5-10% reduction in collection times.

Mono 3.6.0 has 878 commits since the last release. This is the work
of 66 contributors since March 10 2014. Out of those, 22 have done
their first contribution. 112 bugs were fixed.
Highlights
Runtime performance counters have been integrated into the
profiler allowing the performance counter information to be
surfaced to profiling tools and in particular Xamarinâs upcoming
profiler.
The profiler now produces backtraces for statistical mode. The
profilerâs tracing mode now works on ARM.
We now distribute nuget on mac.
Debugger
The debugger now support line and column ranges. pdb2mdb supports
it. Note: the rest of our toolchain still needs to be updated.
The debugger now supports changing the current line in the top
frame.
Lots of bugfixes and performance improvements.
The debugger now support reading simple properties without
calling their getter, this is done by having a lightweight IL
interpreter for small pieces of code. This allows more properties
to be inspected while the process is completely stopped and
without having to temporarily resume execution of the target
to execute the property code.
Added buffered response mode to improve network efficiency on
high latency links such as USB.
Garbage Collection
The GC bridge got a lot of performance work. There are now two
new modes that can significantly improve some workloads.
Class libraries
Multiple http stack improvements: some leaks in the stack have
been fixed, as well as solving some long-standing bugs involving
asynchronous operations and proxies. We have introduced a more
comprehensive test harness to ensure that those bugs do not
surface again.
System.IO.Compression is now implemented
System.Security.Claims is now implemented. It resides in the
System assembly (existed before in the Identity stack, but now
we track the new home from the .NET 4.5 API).
Performance
Reworked locking to drop a hot lock in method lookup.
Use fine grained locking instead of a big hot lock.
Better hashing of some runtime internal items to avoid some
corner-case slowdowns with generics.
Profiler
The profiler is now able to produces backtraces in statistical
mode.
Added periodical flushing that should help interactive users.
This means that the profiling will send data over the profiling
even if the application is not currently sending data (this is
there to support the upcoming new profiler UI).
It now collects and reports performance counter information.
See mprof-reportâs man page.
Misc
Fixed the handling of the volatile. CIL prefix.
We now distribute IKVMâs ikdasm tool. This is a reliable
disassembler that does not have the limitation of monodis of
requiring a complete set of assemblies that are compatible to
disassemble. This will disassemble even files that do not have
their dependencies available.
Optimized EqualityComparer for more types.
Mono.Unix.Native.Syscall.getxattr() can now return Errno.ENOATTR
on OS X.
Our msbuild implementation can now build Project K and Roslyn
Optimized EqualityComparer for more types.
As well as lots of bug fixes
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
Setting PLATFORM causes the build system to look for a ${PLATFORM}.make
file; this leads to build failure if a PLATFORM environment variable
leaks in from the outside environment.
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
