Speaking of ffsl() issues, mingw32 now complains about ffsl() being
undefined in hbitmap:

In file included from /home/stefanha/qemu/include/block/block_int.h:35:0,
                 from qemu-img.c:32:
/home/stefanha/qemu/include/qemu/hbitmap.h: In function 'hbitmap_iter_next':
/home/stefanha/qemu/include/qemu/hbitmap.h:173:5: warning: implicit declaration 
of function 'ffsl' [-Wimplicit-function-declaration]

Using mingw32-gcc-4.7.2-7.fc18.  I haven't looked into this but I
thought ffsl() was a gcc built-in and it wouldn't require any headers.
