We can't be expected to chase down every cpantesters report, also we cant be expected to directly support every platform out there, we depend on users from such platforms to at least report bugs, if not provide patches to get things working on their platforms.

FWIW, we semi-regularly check Sereal-Decoder Test Maxtrix and Sereal-Encoder Test Maxtrix which do not show any issues building on Win32. Also I checked and some if not all of the C portability bugs have been fixed in 3.005_001, which was released quite a while ago, Jan 27, only three weeks after 3.005. That we have not received one email regarding Win32 build issues is suggestive that either the issues mentioned in this thread are rare, or that Win32 demand is very very low. I guess it could also indicate that Win32 users are less likely to report build issues. Regardless, open source doesn't work when people deal with build problems by bitching about them in website discussions. They need to file bugs.
