The runpath issue only affected the x86-64 arch on NetBSD. The
spec change was only effective on i386, so relocating the change
enables the RUNPATH tag in the gcc libraries on the amd64 platform.
NetBSD doesn't seem to be honoring -rpath, at least not with binutils
from base. Using binutils from pkgsrc doesn't work either because it
uses the gold linker (for an unknown reason) which fails with an
"unsupported operation". As a result, gcc5-aux was limited to base
binutils for NetBSD 7 and later. The issue was never resolved.
The signal trampoline detection for NetBSD 7 and later is still broken.
Support for NetBSD 6.99 has been removed along with supporte for
32-bit DragonFly. The modifications to the testsuite were misguided and
have also been removed.
This compiler package is not like the lang/gcc4* packages, but rather
the lang/gcc-aux package which exists to bring GNAT, the Ada language
compiler. The lang/gcc-aux package is based on gcc-4.9, and this
package is based on gcc-5. This is the first gcc5 package in pkgsrc,
and it does support C, C++, ObjC, and Fortran in addition to Ada thus
it is very useful, but it does have a different purpose than other
gcc ports.
This port has had minimal testing. I verified GNAT passes 100% of the
testsuite on NetBSD 6.1/amd64, but it has not been tested on any
NetBSD 5, 7.0 or 7.99 platform yet. I don't have any hardware, so it
will require using a VM or having others report failure/success. Due
to similarity with lang/gcc-aux, chances are good that it will build
and function properly on other platforms.
See http://gcc.gnu.org/gcc-5/changes.html for more information about
improvements over the gcc-4.9 series.
