Bashisms are the disease of Linux-originated scripts. It is very possible
that this specific bashism is due to the libxml2 M4 macros; it may be our
usage of them. Can you track down the exact changes ?

Yes, indeed. I'll try to fix that before the next tarball.

Hard linking is a Bad Thing generally speaking (there are situations where
it is okay, but I'm hard pressed to find one). Hard linking across
directories is almost always a no-no, because each directory could
potentially be a mount point. I guess libtool is doing it because it
hardlinks between a directory an a subdirectory of it it has mkdir'd itself,
which makes it believe it's on the same partition. I'm afraid this means
libtool expects some POSIX behaviour AFS doesn't have. Which version of
libtool are you using (if you ran autogen.sh; if you didn't, I know which
libtool you've used) ? 

If we can't fix this issue with libtool on solaris (by talking to the
libtool guys), I'm afraid the only fix is to document against building on an
AFS partition (just like you don't build on a vfat partition).

what version of libpng, and what version of the libpng-devel stuff ?
(assuming there is a mismatch).

Uh. This means your #define isinf will have trouble as well, since finite()
is defined in libm, isn't it? Looks like we need to include libm for dia
proper, anyway.
