The bug is actually more subtle: distcc has global variables
indicating whether whether it has seen an -x option and the last value
of its argument, and forgets to clear them between running multiple
jobs on the server, so it assumes an incorrect language override when
no -x option is present. This bug is in the Apple-patched distcc
version that's shipped with the 10.5 Developer Tools (source at
http://opensource.apple.com/tarballs/distcc/distcc-1201.tar.gz), so
it's -- sadly -- not a really old version.

With ccache eating the -x option, I don't see an easy workaround for
this bug, and upgrading distcc would mean having to upgrade it on all
machines at once for compatibility reasons :-(

Bernhard.
