The version of binutils does no matter. Have tryed 2.17.50-20060716-1,
2.17.50-20070129-1 and 2.18.50-20080109.

Have exactly the same errors.

Have tried different --with-sysrooot=... and --sysroot=...
All they ends with different errors, for example:

../../../gcc-4.2.2/libssp/gets-chk.c: In function '__gets_chk':
../../../gcc-4.2.2/libssp/gets-chk.c:66: warning: implicit declaration
of function 'alloca'

libtool: link: warning: undefined symbols not allowed in i686-pc-mingw32

Script was started as:
TARGET_CPU=i686 ./x86-mingw32-build.sh --batch i686-pc-mingw32

The gcc exist. With a simple source "int main (void) { return(0); }",
compiled with "i686-pc-mingw32-gcc main.c" got this error:
/home/hn/mingw/lib/gcc/i686-mingw32/4.2.2/../../../../i686-mingw32/bin/ld:
crt2.o: No such file: No such file or directory
collect2: ld returned 1 exit status

The file exist as /home/hn/mingw/lib/crt2.o, "/home/hn/mingw" is the
INSTALL_DIR.

32bit or 64bit host does no difference.

I feel, it has something to do with the sysroot parameter. Changelog for
gcc 4.x.x give some hints about changes on that parameter and a new
parameter --with-build-sysroot.

Have anybody finish the script x86-mingw32-build.sh with gcc 4.2.x ?

I have other scripts managed in www.colinux.org ready with gcc 4.2.2 and
binutils 2.17.50-20070129-1. The difference is, that we using
mingw-runtime as binary, and additional parameter --with-headers.
