Hi folks!
I'm trying to build a cross-compiler under Linux and MacOSX using this
script: http://sourceware.org/ml/cygwin/2010-08/txt00010.txt
I get the same error on Linux and MacOSX after the make of line 340:

Anyone able to run the script to completion or a different (and working) way
to build a cross-compiler for cygwin on Linux and OSX?

Cygwin normally builds with -Werror but there are a few warnings
generated by GCC 4.5 which haven't been fixed yet in the code. Remove
-Werror from $top_builddir/i686-pc-cygwin/winsup/cygwin/Makefile and the
rest of the build should precede without any further difficulties.

Sorry for replying so late.

Not without any further difficulties, but at least with a different error:

Again, the same error on Linux and OSX.
Thank you for helping, btw! ;)

You need to have mingw.org runtime and w32api files installed, such as
Fedora Linux's mingw32-runtime and mingw32-w32api packages. Otherwise,
unpack the binary packages found here into your system root:
http://cygutils.fruitbat.org/ITP/mingw-gcc/release/mingw/mingw-runtime/
http://cygutils.fruitbat.org/ITP/mingw-gcc/release/mingw/mingw-w32api/

Depending on your distro, this might make things a bit easier:

As for OSX, you'll need the patches from git, but the directions from
the .spec files will likely need some adjustments.
