core.stdc is an interface to the C99 API, so everything is preserved verbatim.  c_long and c_ulong were added because the size of C long differs between Windows and non-Windows x86_64 platforms.  Typically, int, short, etc are the same however, which is why there's currently no c_int--it was just a needless complication at the time.  The aliases for D users, if the exist at all, should be separate.
