On re-reading 'man Xserver', the point I had failed to grasp is that only
symlinks in the catalogue fontpath are considered (so copies, hard links or
native links are all ignored)

In which case, this patch is wrong and a stub readlink() which always returns
the error EINVAL (which shouild be functionally equivalent to Colin's patch
which just skips reading the directory contents) would be more correct.

Alternatively, I suppose it might make sense to add some sort of configure
option to disable building with catalogue fontpath support, so that an error
would be generated if an attempt was made to use one?
