So, I tried putting this in my code:
#if SDK_NAME == macosx10.5
SInt16 vwForkRef = 0;
#elif
FSIORefNum vwForkRef = 0;
#endif
However, I get the compile error:
error: missing binary operator before token ".5"
Notwithstanding all the other issues people have brought up, the
above preprocessor directive does not have valid syntax. Judging
from the error message, macosx10.5 has been parsed as two tokens
"macosx10" and ".5" and the compiler is understandably complaining
that you have no operator between them.
The values of the AvailabilityMacros definitions are in the form 1040,
1050 etc. for exactly this reason, which is yet another reason to use
the provided and supported mechanism instead of rolling your own
solution.
