Use autoconf 2.5 so that we could get m4sugar macros (AS_VAR_PUSHDEF et al.) and more importantly correct macros for AC_SYS_LARGEFILE support. BTW, also fix test for <linux/if.h>
Handle dummy files. Merge in configure stuff for Mach exception filters. Check whether struct sigaction defines sa_restorer member. Don't include posix_sem.cpp on native Linux/ppc builds.
- Integrate new NativeOp instructions to be used as trampolines to call native functions from ppc code. - Little endian fixes in emul_op.cpp - Add new 'gpch' 750 patch to workaround crash with MacOS 8.6 - Don't crash in Process Manager on reset/shutdown with MacOS 8.6 - We also have an experimental interrupt thread in emulation mode
