Preprocesser Macros

The following are the C preprocessor macros used for making various compile-time checks against MacOSX architectures - Firebird currently checks for the 32bit macros... I hope to try a 64bit intel build on Leopard in the not too distant future. This will mean defining yet another "new" platform.

__ppc__
__ppc64__
__i386__
__x86_64__
