That was caused by change #4366 (Sebastian remade the configure files).
I have tried the same some days ago and TeX/libs/xpdf/configure failed
for me, too. So I did a "p4 revert TeX/libs/xpdf/configure" before
submitting stuff.

The reason for the failiure is that Martin (no offense, just a fact :-)
has used a different approach then me for adopting xpdf to our
needs. While I have eliminated checks for the xpdf viewer and adjusted
the configure.in to work with autoconf-2.13, Martin has taken a different
route.

The conclusion is that TeX/libs/xpdf/configure should be taken out of
reautoconf, because this is supposed to work with autoconf-2.13. Or,
Martin might as well decide to switch to my approach for the configure
stuff for xpdf (it is available in yesterday's teTeX-beta). I plan to
keep my approach for teTeX, so the extra work needed for the adoption
to old autoconf will be done by me anyway.

config.sub and config.giess should be considered as a matching pair. One
can replace them with a new version, but this should be done everywhere,
then.

Karl, do you have a good location for these files? Can you auto-update them?
In fact, I somehow thought that you were already doing this.
