Bill, I just read through your posting about the MinGW issues in "DLL Hell". Did you ever manage to get MinGW compile JCC and link against msvcr90.dll?
I think I'm facing a similar issue (see post of today) and tried to change MinGW spec to use msvcr90 (as mentioned in http://www.mingw.org/wiki/HOWTO_Use_the_GCC_specs_file) but then "python setup.py build --compiler=mingw32" runs in to ldd issues (I guess that's because I still need to "hack" minGW itself...) - see attached output. > I'll try that -- getting mingw to use the same C library that Python > uses. Looks like you can do an in-place update -- the pyMinGW toolkit > provides a tool which does that. > (How) did you manage that?
