How do you mean "make of mingw does not require $(EXEEXT)"?  AFAICT,
if the Makefile defines a target FOO, and there's a file FOO.exe that
is up to date wrt its dependencies, the MinGW Make will recompile
anyway, because it doesn't understand that linking FOO produces
FOO.exe.

So I think MinGW and OS/2 are in the same wagon here.
