Call for Patches for crosstool-0.43

[Colin Paul Gloster]

Build reports for crosstool 0.42...

from FreeBSD i386-unknown-freebsd4.11 with native gcc version 2.95.4 
20020320 [FreeBSD] to gcc-3.2.3-glibc-2.2.5 with the attached patch for 
crosstool 0.42: apparently succeeded but not tested with demanding 
sourcebases;

from GNU/Linux x86_64-unknown-linux-gnu with kernel 2.6.11-1.1369_FC4smp 
and GLibC 2.3.x and native gcc version 4.0.0 20050519 (Red Hat 4.0.0-8) to 
gcc-3.2.3-glibc-2.2.5: failed (after approximately 36 minutes);

and

from GNU/Linux i686-pc-linux-gnu with kernel 2.6.14-1.1656_FC4smp and 
GLibC 2.3.x and native gcc version 4.0.2 20051125 (Red Hat 4.0.2-8) to 
gcc-3.2.3-glibc-2.2.5 (though the target is actually really the 
i686-pc-linux-gnu GLibC 2.3.x host and build system with an old 
proprietary third party library incompatible with Red Hat GLibC 2.3.x 
against which I need to link): succeeded, various free sourcebases with 
which it was tested include: X.org 7.0 (this was the trickiest to link 
without accidentally linking against an already installed copy of X.org); 
LessTif 0.94.4; Expat 2.0.0; NetCDF 3.6.1; and FFTW 3.1.1.

To build with crosstool on FreeBSD targetting GNU/Linux (specifically from FreeBSD i386-unknown-freebsd4.11 with native gcc version 2.95.4 20020320 [FreeBSD] to gcc-3.2.3-glibc-2.2.5), one must substitute various FreeBSD programs with GNU replacements and install other GNU software, viz. at least: gmake; install (from GNU coreutils); patch; sed; autoconf; bison; m4; and wget. Note also that on FreeBSD 4.11, in contrast to e.g. at least one Red Hat Fedora Core distribution of GNU/Linux, colorized ls causes "checking whether build environment is sane... configure: error: ls -t appears to fail" errors. Also, this patch to fix-embedded-paths.c may be useful.
