[Bug bootstrap/42663] New: GCC 4.5-20100107 doesn't bootstrap on MinGW/MSYS

["lxndrmxwll at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

According to the GCC 4.5 Release Criteria at
http://gcc.gnu.org/gcc-4.5/criteria.html , MinGW is a secondary platform and
should be able to bootstrap successfully. GCC 4.5-20100107 contains the fix for
42584 and builds on MinGW/MSYS with --disable-bootstrap, but it still doesn't
bootstrap.

Here is my build process in precise detail.

Step 1. Extract to C:\Temp\gcc\msys (or any other location separate from the
working directories used here):

http://sourceforge.net/projects/mingw/files/ > MSYS Base System > msys-1.0.11 >
msysCORE-1.0.11-bin.tar.gz
http://sourceforge.net/projects/mingw/files/ > MSYS Bison > bison-2.4.1-1 >
bison-2.4.1-1-msys-1.0.11-bin.tar.lzma
http://sourceforge.net/projects/mingw/files/ > MSYS Flex > flex-2.5.35-1 >
flex-2.5.35-1-msys-1.0.11-bin.tar.lzma
http://sourceforge.net/projects/mingw/files/ > MSYS regex > regex-1.20090805-1
> libregex-1.20090805-1-msys-1.0.11-dll-1.tar.lzma

Step 2. Save decompressed .tar files to C:\Temp\gcc\sources (this is a staging
area separate from the working directories used here):

http://sourceforge.net/projects/mingw/files/ > MinGW Runtime > mingwrt-3.17 >
mingwrt-3.17-mingw32-dev.tar.gz
http://sourceforge.net/projects/mingw/files/ > MinGW API for MS-Windows >
w32api-3.14 > w32api-3.14-mingw32-dev.tar.gz
ftp://gcc.gnu.org/pub/gcc/snapshots/4.5-20100107/gcc-core-4.5-20100107.tar.bz2
ftp://gcc.gnu.org/pub/gcc/snapshots/4.5-20100107/gcc-g++-4.5-20100107.tar.bz2
ftp://ftp.gmplib.org/pub/gmp-4.3.1/gmp-4.3.1.tar.bz2
http://www.mpfr.org/mpfr-current/mpfr-2.4.2.tar.bz2
http://www.mpfr.org/mpfr-current/patches (renamed to mpfr-2.4.2.patch)
http://www.multiprecision.org/mpc/download/mpc-0.8.1.tar.gz

Step 3. In MSYS, run the following commands. This uses C:\Temp\gcc\src ,
C:\Temp\gcc\build , and C:\Temp\gcc\dest as working directories.

cd /c/temp/gcc/sources
tar -C /c/temp/gcc -xf gcc-core-4.5-20100107.tar
tar -C /c/temp/gcc -xf gcc-g++-4.5-20100107.tar
tar -C /c/temp/gcc -xf gmp-4.3.1.tar
tar -C /c/temp/gcc -xf mpfr-2.4.2.tar
patch -Z -d /c/temp/gcc/mpfr-2.4.2 -p1 < mpfr-2.4.2.patch
tar -C /c/temp/gcc -xf mpc-0.8.1.tar
mkdir -p /include
rm -rf /mingw
mkdir /mingw
tar -C /mingw -xf mingwrt-3.17-mingw32-dev.tar
tar -C /mingw -xf w32api-3.14-mingw32-dev.tar
cd /c/temp/gcc
mv gcc-4.5-20100107 src
mv gmp-4.3.1 src/gmp
mv mpfr-2.4.2 src/mpfr
mv mpc-0.8.1 src/mpc
mkdir build dest
cd build

../src/configure --prefix=c:/temp/gcc/dest --enable-languages=c,c++
--enable-threads --disable-nls --disable-win32-registry
--disable-sjlj-exceptions --with-arch=i486 --with-tune=generic
--enable-cxx-flags='-fno-function-sections -fno-data-sections'
--disable-libstdcxx-pch --disable-shared --enable-checking=release
--disable-symvers --enable-fully-dynamic-string

make

This fails with:
