It's in the system unit (rtl/bsd/system.pp, procedure FPC_SYSTEMMAIN;  
FPC_DARWIN_PASCALMAIN and are both always defined)

The way it works is that crt1.o calls 'main', and the Pascal program  
simply contains a branch to FPC_SYSTEMMAIN as its main function (or as  
whatever you specify using -XM).
