Oh yes, I remember I had similiar problems. I used these flags for CXX 
and for my g95 with low optimization -O instead of at least -O2 or even 
-O3 that I used before the change to gnulib. But I can check once again 
with higher optimization tomorrow

  CXXFLAGS = -arch i386 -m32 -O -mieee-fp -fforce-addr -isysroot 
/Developer/SDKs/MacOSX10.6.sdk

  FFLAGS = -O -mieee-fp -fforce-addr

I'm using Apple's gcc and a handful of selfmade tools - and I linked 
libtoolize to glibtoolize, otherwise things don't work for me

 ~/Development/octave$ ls -l /usr/bin/libtoolize
lrwxr-xr-x  1 root  wheel  11  9 Jan 16:49 /usr/bin/libtoolize -> 
glibtoolize

Here is the ouput of my other tools

which gcc; gcc --version
/usr/bin/gcc
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5646) (dot 1)

which autoconf; autoconf --version
/usr/local/bin/autoconf
autoconf (GNU Autoconf) 2.65

which automake; automake --version
/usr/local/bin/automake
automake (GNU automake) 1.11

which flex; flex --version
/usr/local/bin/flex
flex 2.5.35

which gawk; gawk --version
/usr/local/bin/gawk
GNU Awk 3.1.7
Copyright (C) 1989, 1991-2009 Free Software Foundation.

which sed; sed --version
/usr/local/bin/sed
GNU sed version 4.2
