Doesn't compile for OSX 64bit

[grahamegrieve]

I am trying to port all my code to OSX 64 bit (per Catalina). The code does't compile for 64bit OSX - mixed asm in RaiseException in FastMM_OSXUtil and Undeclared identifier: 'TRtlCriticalSection' in FastMM4.

Delphi 10.3.2, MAC = Mojave 10.14.5, XCode = 11.1 (11A1027)

Confirmed, the PUREPASCAL define is not totally "pur" .
I would love to use this MM even in purePascal mode.
