Depending on other optimization options, compiler could get confused
into an internal error, and was, probably, building pessimized code
even when working.
Ensure warning-free build, while I'm here. Mark the SSE as having no
effect -- ``--enable-sse'' causes configure to add the HAS_SSE define
to CFLAGS, but nothing in the current release checks for that flag. Ha-ha.
There are SSE implementations of some parts of the code (they are just
no used), so, perhaps, someone can add another patch to make use of them,
when possible.
the libtoolX ports instead of the one included with each port. Ports that
set USE_LIBTOOL_VER=X will now use the ports version of libtool instead of
the included version. To restore previous behavior, use the new macro,
USE_INC_LIBTOOL_VER. Both macros accept the same argument: a libtool version.
For example, to use the ports version of libtool-1.5, add the following to
your Makefile:
USE_LIBTOOL_VER= 15
To use the included version of libtool with extra hacks provided by
libtool-1.5, add the following to your Makefile:
USE_INC_LIBTOOL_VER= 15
With this change, ports that had to add additional libtool hacks to prevent
.la files from being installed or to fix certain threading issues can now
delete those hacks (after appropriate testing, of course).

Begin autotools sanitization sequence by requiring ports to explicitly
specify which version of {libtool,autoconf,automake} they need, erasing
the concept of a "system default".
For ports-in-waiting:
USE_LIBTOOL=YES -> USE_LIBTOOL_VER=13
USE_AUTOCONF=YES -> USE_AUTOCONF_VER=213
USE_AUTOMAKE=YES -> USE_AUTOMAKE_VER=14
Ports attempting to use the old style system after June 1st 2004 will be
sorely disappointed.
