You are not concerned by the current language at all in the low level
macro, and the high level macro should set the compiler or flags var
associated to the current language.  There is no direct support for
this, you have to

AC_LANG_CASE([C],          [CFLAGS="$CFLAGS $WIN32FLAGS],
             [C++],        [CXXFLAGS="$CXXFLAGS $WIN32FLAGS],
             [Fortran 77], [FFLAGS="$FFLAGS $WIN32FLAGS],
             [AC_FATAL([NIah?  Never heard of] _AC_LANG)])
