I’m following this guide mostly to compile gcc on windows:

http://www.aristeia.com/Misc/gcc4ForWindows.html

The difference is that I am using msys 1.10 and trying to build gcc trunk from SVN. the source tree compiles fine on linux, however when I attempt to build on windows, i get the following error upon running the configure script.

<snip>

The command line I am using is this:

../configure –prefix=C:/rosbe/i586 –build=mingw32 –host=mingw32 –target=mingw32 –enable-languages=c,c++ –disable-win32-registry –enable-sjlj-exceptions –enable-threads=win32 –enable-checking=release
