Allow ctypedef my_struct_s my_struct_t[1] trick, can access members of my_struct_t as if it were a pointer.

The following small patch gets rid of some warnings on the cygwin
platform (it it not WIN32 but does have definitions of __stdcall
resulting in warnings).

Please let me know if it will or won't get into the upstream release.

Thanks.

fixes for True/False in compile time expressions; make sure True/False pass as objects (not just ints) where possible
