- mangling D's long/ulong as C++'s int64_t/uint64_t was reverted with 2.082 due to breaking interop of C++'s and D's size_t/ptrdiff_t - this revert unveiled a mismatch in dmd's backend where the C++ side uses int64_t/uint64_t as targ_ptrdiff_t/targ_size_t while the D side uses long/ulong, thus 2.082 cannot compile dmd on OSX-64 - fixed by using int64_t/uint64_t everywhere - druntime's int64_t/uint64_t are correctly mangled as long long/unsigned long long since on OSX-64 2.079
- due to relying on magic enums (cpp_ulonglong on OSX), plain comparison between targ_ullong and targ_llong is an error

This blocks the upcoming 2.083 beta/release
due to breaking interop of C++'s and D's size_t/ptrdiff_t
uses int64_t/uint64_t as targ_ptrdiff_t/targ_size_t while the D side
uses long/ulong, thus 2.082 cannot compile dmd on OSX-64
long long/unsigned long long since OSX-64 2.079
