How important is it to run autoreconf? Could the fact that the

no - it's one of the changes made to autoconf, rather than libtool
I'm not sure I understand what you're saying. Maybe I didn't make it
clear that the segfault occurs after a build of the *original source*.
It was only after that happened that I decided to try Yaakov's
suggestion of running autoreconf, but that failed. (And it changed the
source in ways that prevented a subsequent build from succeeding.)
BTW, I've also asked for help on the tex-live mailing list [1], and I
was advised to run xdvi under a debugger and get a backtrace. I'm
attaching a transcript of the gdb session, as well as the resulting
stackdump, on the off chance that someone will spot something helpful.
Otherwise, I have to give up and hope that someone more knowledgeable
will figure out how to compile xdvi for cygwin under X11R7.4.
