I'm working an a crossplatform C++ project. How I conditionally compile for Macintosh?
Something like:
#ifdef Macintosh
	do mac stuff
#endif
But 'Macintosh' isn't the right symbol, is it? What is?

You may want __APPLE__ but the best way to make a decision is to examine the output from 'cpp -dM <file>'. That dumps a list of the pre-defined macros that are currently recognized and it's sometimes better to pick a more specific symbol like __POWERPC__ or __BIG_ENDIAN__ depending on the actual reason for your #ifdef.
