Here's something you might want to try, though it may not be related.
Modify your configure.in like this:
## If we're using GCC, ask for aggressive warnings.
case "$GCC" in
yes )
## We had -Wstrict-prototypes in here for a bit, but Guile does too
## much stuff with generic function pointers for that to really be
## less than exasperating.
## -Wpointer-arith was here too, but something changed in gcc/glibc
## and it became equally exasperating (gcc 2.95 and/or glibc 2.1.2).
## -fno-strict-aliasing keeps us from having to change our code for now.
CFLAGS="$CFLAGS -Wall -Wmissing-prototypes -fno-strict-aliasing" ;;
esac
and then re-autoconf and re-build. Or, if you don't want to risk your
version of autoconf not being compatible, just edit your configure to
include -fno-strict-aliasing where it now only has -Wall -Wmissing...,
etc. I've modified current 1.6 CVS to include this, and it's
something we need for now regardless, but your copy doesn't have it.
