Changes since 1.3:	+1 -2 lines
Log Message:	- removed MemoryDispatch() replacement; routine from ROM is now used if possible - rom_patches.cpp: check for double PACK 4 resources; if only one is found, assume that the ROM requires an FPU and issue a warning if FPU emulation is turned off - UAE CPU opcode routines no longer return the cycle count - main_unix.cpp: pressing Ctrl-C dumps the UAE CPU state before entering mon - sys_unix.cpp: under Linux, partition sizes are read with BLKGETSIZE instead of llseek()
