Microsoft Specific

The __pascal, __fortran, and __syscall calling conventions are no longer supported. You can emulate their functionality by using one of the supported calling conventions and appropriate linker options.

<windows.h> now supports the WINAPI macro, which translates to the appropriate calling convention for the target. Use WINAPI where you previously used PASCAL or __far __pascal.
