Hi, The function System.Info.os on WinHugs returns "mingw32", which is not really true. I guess its because the libraries are compiled using mingw32, since they can't be compiled natively from windows? Is there some way to alter the library build scripts? Thanks Neil

As MinGW produces native binaries, "mingw32" isn't an appropriate value for os in any case -- it should be "mswin32" or the like, whether the Win32 binary was compiled with MSVC or MinGW. However "mingw32" is the name used by autoconf, and it's pervasive in the libraries. Maybe it should be special-cased in System.Info. Then again, Cabal uses the values of System.Info.{arch,os} to construct the CPP symbols to be defined when preprocessing packages for Hugs, and package authors have #ifdef mingw32_HOST_OS all over the place.
I noticed GHC also gets it wrong in this case, with the same result.
It's a bit of a shame, but maybe its too late to change...
