have the right tools. The most important one is gcc. I cannot guaranty
that QEMU works if you do not use a tested gcc version. Look at
'configure' and 'Makefile' if you want to make a different gcc
version.

[1] On Alpha, QEMU needs the gcc 'visibility' attribute only available
for gcc version >= 3.3.
[2] Linux >= 2.4.20 is necessary for precise exception support
(untested).

- fix iret/lret/fpush not before mem load restarting
- fix arm fpu rounding (at least for float->integer conversions)
- fix CCOP optimisation
- optimize FPU operations (evaluate x87 stack pointer statically)
- fpush not before mem load restarting
- fix all remaining thread lock issues (must put TBs in a specific invalid
state, find a solution for tb_flush()).
- handle fp87 state in signals
- add gcc 2.96 test configure (some gcc3 flags are needed)
- optimize FPU operations (evaluate x87 stack pointer statically)
- add IPC syscalls
- submit a patch to fix DOSEMU coopthreads
lower priority:
--------------
- use -msoft-float on ARM
- use kernel traps for unaligned accesses on ARM ?
- handle rare page fault cases (in particular if page fault in heplers or
in syscall emulation code).
- fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID)
