Similar recent topic:

This should be uninterested to me since too many changes have been been done since gc7.1 release (but I'll look it thru).

1. Don't try to compile gc7.1 with MinGW.

2. Get latest CVS snapshot from (you can aso try to compile surces from gc72alpha2 tarball but it contains a number of Win32-specific bugs fixed later).

3. Unfortunately, AFAIK, at present there's no working building script for MinGW (but you can try to "sh configure" and contribute the fixes, if any), so the most "reliable" and tested way is to invoke gcc manually, e.g. something like this builds a release gc.dll and test.exe:



4. Tested with the following GCC toolchains for Windows (x86 and amd64):
- MinGW v5.1.4 (GCC v4.4.0, mingwrt-3.15.2, w32api-3.13, binutils-2.19.1);
- mingw-w64(w32) i686-w64-mingw32-gcc.exe (GCC) 4.5.0 20091013 (experimental);
- mingw-w64 x86_64-w64-mingw32-gcc.exe (GCC) 4.5.0 20091014 (experimental).

Any more questions?
