[Qemu-devel] [PATCH v2] hw/i386: Fix broken build for non POSIX hosts

[Stefan Weil]

pc-testdev.c cannot be compiled with MinGW (and other non POSIX hosts):

  CC    i386-softmmu/hw/i386/../pc-testdev.o
qemu/hw/i386/../pc-testdev.c:38:22: warning: sys/mman.h: file not found
qemu/hw/i386/../pc-testdev.c: In function ‘test_flush_page’:
qemu/hw/i386/../pc-testdev.c:103: warning: implicit declaration of function 
‘mprotect’

v2

This patch replaces my previous patch

  hw/i386: Fix broken build for MinGW

Instead of disabling pc-testdev.o for non KVM hosts,
this version only excludes the mprotect code for non
POSIX hosts. Alex Graf suggested a similar solution.
