Hmmm, having some fragile OS-dependent #ifdefs is not the way to go.
While you are there, every

    #ifdef mingw32_TARGET_OS

which needs to be changed should be replaced by something feature-specific
like

    #if HAVE_FOO_BAR_FUNCTION

and the autoconf stuff be extended accordingly. If you don't have M4
as your hobby, keeping

    #ifdef mingw32_TARGET_OS
    #define HAVE_FOO_BAR_FUNCTION
    #undef HAVE_BLAH
    ...
    #endif

in a single prominent place is much better than spreading this all
over the code
