Here's something you might want to try, though it may not be related.
Modify your 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" ;;

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.
