I have also noticed that sparc-linux-user does not compile on an AMD64
host (CentOS 5.4):

cc1: warnings being treated as errors
/mada/users/gsouther/projs/qemu/linux-user/mmap.c: In function =91mmap_find=
_vma=92:
/mada/users/gsouther/projs/qemu/linux-user/mmap.c:367: warning:
comparison is always false due to limited range of data type
make[1]: *** [mmap.o] Error 1
gmake: *** [subdir-sparc-linux-user] Error 2

The compilation warning can be fixed by removing the ul specifier from
-1ul, but I'm wondering if you had noticed the same problem.
