I've pushed a change to devtools/gpsd-debian-regressions.sh to make it print the
architectures where no tests failed. Currently it prints


armel: no regressions
armhf: no regressions
hurd-i386: no regressions
i386: no regressions
ia64: no regressions
kfreebsd-amd64: no regressions
kfreebsd-i386: no regressions
powerpc: no regressions
ppc64: no regressions

On mips all tests failed, I think it just failed to open a pty. Why that is the
case is something I need to figure out and work around with the next upload. It
would be nice if the regress-driver would just fail if there is a pty issue
instead of spitting out a  lot of diffs.

Where ever the issue is, it doesn't seem to be related to endianess issues.
Sparc, s390 and s390x (the 64bit s390 port) seem to be the only architectures
with issues so far.

As you can see on
http://buildd.debian-ports.org/status/package.php?p=gpsd&suite=sid
we even have some really exotic unofficial architectures - unfortunately not all
build-dependencies are available there. If there is an interest in making gpsd
build on one of the listed architectures, please let me know (I think the main
issue is QT not being available...).
