This sounded like an interesting software archeology problem...
Tom Lane of IJG posted a slightly later version of jpeg's configure.in
and associated files to the UnixOS2 mailing list in 2004:
http://unix.os2site.com/pub/list/unixos2/2004/03/2004Mar31000402.txt
> Let's see ... configure is built like this:
>
> configure: configure.in sed.cfg aclocal.m4
> autoconf configure.in | sed -f sed.cfg >configure
> chmod +x configure
I've lightly modified the files he posted so that they exactly reproduce
the configure script in jpeg-6b, which is what's bundled in outguess and
various other packages, when built with autoconf 2.12. The modified
files are attached; you also need libtool.m4 from libtool 1.2.
