Bug Description

The lucid/sparc build of the packages failed:
http://launchpadlibrarian.net/63766014/buildlog_ubuntu-lucid-sparc.qemu-linaro_0.13.50-2011.02-0-0ubuntu1~ppa10.04.1_FAILEDTOBUILD.txt.gz

  CC i386-linux-user/mmap.o
cc1: warnings being treated as errors
/build/buildd/qemu-linaro-0.13.50-2011.02-0/linux-user/mmap.c: In function 'mmap_find_vma_reserved':
/build/buildd/qemu-linaro-0.13.50-2011.02-0/linux-user/mmap.c:235: error: comparison of unsigned expression >= 0 is always true

This is gcc-4.4_4.4.3-4ubuntu5, but I think the key thing is that SPARC host doesn't define CONFIG_USE_GUEST_BASE, so RESERVED_VA is 0 and gcc complains.

Not sure if there's a clean way to deal with this since in this case it's gcc being alarmist.

Posted a fix for this to upstream:

but we'll see if anybody else comes up with a better approach before I commit it to qemu-linaro.
