These changes are from "portable1" patch. - put /*comments symbols*/ around any chars after #endif. Other compilers do not get it. - fix cases in which a pointer is cast to a 32-bit int, then back to a pointer. This breaks on a machine with 64-bit pointers. Examples: FPU_sub arg 2 and FPU_div arg 2. The int->ptr->int conversions are now done more safely by macros REGNO2PTR and PTR2INT. - use GCC_ATTRIBUTE macro instead of __attribute__. For compilers that do not support __attribute__, the macro can be defined to be nothing. - in fpu_entry.c, arg1 of FPU_load_int32 is (s32*), but the calls to it cast their data to (u32*). - if compiler does NOT inline functions in poly.h, the "extern inline" setting caused duplicate symbols to be created. Changed them to "static inline" so that the mul_32_32 from different .c files do not conflict. - implemented setcc so that it doesn't use curly brackets inside parens - comment out sigcontext structure definition, which conflicts with non-linux or non-intel operating systems. It's not used by bochs anyway.
