    Cygwin: restore two instances of __stdcall
    
    In the previous commit, __stdcall was removed from _dll_crt0 in
    winsup.h and dcrt0.cc but not in lib/cygwin_crt0.c.  For consistency,
    restore the first two occurrences of __stdcall.  We could instead
    remove it from the declaration in lib/cygwin_crt0.c, but this might
    appear to affect binary compatibility, even though it really doesn't.
