Subject: [PATCH] build: haiku system build fix

Most of missing features resides in the bsd library.
Also defining constant equivalence.

Hi; thanks for this patch. I have some review comments
below, mostly relating to better ways to implement
the compatibility fixes.

I think this either should not be necessary, or if it's
fixing something the fix should be elsewhere. For
POSIX-compatible host OSes, sys/mman.h is included
via include/sysemu/os-posix.h which in turn is pulled in
by include/qemu/osdep.h, which is always included by every
C file in QEMU. I think looking at configure that Haiku
host builds should set CONFIG_POSIX, so I would expect
that sys/mman.h has already been included here.

If Haiku doesn't support an mlockall() equivalent, then the
correct implementation of os_mlock() for it is to return
-ENOSYS -- compare the Win32 stub version in
include/sysemu/os-win32.h.

Also, in general we prefer configure to do feature tests,
rather than for the source code to have OS-specific ifdefs.
So here you'd want a configure test for "does the system
provide mlockall()?", and then the implementation would
be guarded with CONFIG_MLOCKALL.

Does Haiku really provide /dev/dri ? If not then rather than
making this code which can't be used on this host OS compile
it would probably be better to just arrange that it doesn't
get compiled. I suspect that the answer here is that the
$(CONFIG_POSIX) guard on compiling drm.o in util/Makefile.objs
should really be a $(CONFIG_LINUX).

If Haiku's SIGPOLL really behaves like Linux's SIGIO then
include/qemu/osdep.h is the best place to put this kind
of fixup, so that all files get the benefit of it.

Your indentation here has got messed up.

This would be neater if we dropped the GLIBC/HAIKU check
in favour of a configure "is openpty() in pty.h?" test.
