0db0d48bf0 Avoid the use of floating-point when loading/storing from/to memory. This 
could have caused some rounding thus alterations to integer registers on
context switches when lfd/stfd instructions were used. e.g. cygwin compilers
defaulted to i686 code generation and exhibed this behaviour, you could also
see this behavior with -march=i586 -mtune=pentiumpro. GCC is perfectly right
to do those optimizations.

dd7b09ebe8 Use a mutex to protect wakeup_time instead of a semaphore, do we want some 
sort of barrier synchronisation? Anyhow, the current implementation looks
reasonable enough now when using old LinuxThreads without TLS.

XXX: in the past, the sem_post in sigsuspend_handler would not release the
calling thread thus entering into a mutual waiting condition.

663facbf97 Fix native Linux/ppc with recent enough glibc that supports TLS; r2 is used 
in that case. Tell me if I broke other arches, e.g. r13 is no longer saved
in Video and Ethernet stubs, though it seems to be OK.

Colateral feature: SheepShaver should now run on Linux/ppc64 with relevant
32-bit runtime. Native Linux/ppc64 support is harder as low mem globals are
32-bit in mind and e.g. the TLS register there is %r13, %r2 is the TOC
(PowerOpen/AIX ABI)

0d206db2e7 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>

that we can include ../MacOSX/clip_macosx.cpp (clipboard support),
../MacOSX/sys_darwin.cpp (cdrom, floppy et al. support). Also handle new
SDL keycodes file.

3e5c98c7d4 Performance of VOSF is heuristically determined at run-time, so have to 
initialize SIGSEGV handlers early, as in Basilisk II. Besides, also add
missing call to vm_init() in case host system doesn't have MAP_ANON.

df3cf1ac52 Add --enable-sdl-static option to use static SDL libraries. Useful e.g. on 
MacOS X as user might not have SDL installed and I am using self-built
libraries placed into /usr/local/lib/*. Note this can add extra dependencies
to unused libraries.

on Linux/ppc as libSDL is pulling in libpthread which conflicts with

e0a76f9e38 Don't handle XLM_IRQ_NEST atomically in emulated mode. That's useless since 
this variable is modified only within a single thread and interrupts are
not handled asynchronously.
