You're probably OK resetting CFLAGS; anything someone will need
to add to build it would be a define, include path, or library
path, i should think. You never know though, and there's still
the principle of least surprise, since fvwm's configure script
will behave differently than other configure scripts.

Sure, it will add a -L, but not a -Wl,-R or any other platform-
or site-specific flag.

Ah, good old automake. Rerunning the configure script is evil,
for this reason and many others. Since my advice "don't use
automake" probably isn't something anyone is interested in
hearing, resetting only CFLAGS like you suggested will probably
be OK.
While we're on this, let me point out one of the other reasons
rerunning the configure script is evil.
0 fvwm% cat ../configure/fvwm
#! /bin/sh
CFLAGS=-g
CPPFLAGS='-I/usr/pkg/include'
LDFLAGS="-Wl,-R/usr/pkg/lib -L/usr/pkg/lib -Wl,-R/usr/X11R6/lib"
export CFLAGS CPPFLAGS LDFLAGS
sh ./configure \
--disable-gnome-hints \
--without-gnome \
--disable-sm \
"$@"
I have a similar script for every package i install. Luckily for
me, the only automake-using package is fvwm, for which my
CPPFLAGS and LDFLAGS settings are apparently unnecessary because
it will pick them up from the gtk-config script. If it weren't
for that luck, the automake-generated would happily run a
configure script incorrectly and things would explode.

I guess you meant -Werror? I don't see what you're trying to
accomplish though.
