OK, I'm also using

  CC=/usr/bin/gcc
  FC=''
  CXX=''

as the only relevant exported environment variables.

OK, after setting the same environment variables and running configure
and "make all", everything I get matches what you got to this point,
disregarding the different directory names where you are building.
But the above "Not making `cxx/all' because no C++ compiler" is the
last line I see from "make all".  After this I ran "make test" and the
output all looked fine, with no linking errors.  Is the linking error
you see in the next few lines still from running "make all", or is
this output from running "make all test" or ... ?

And my version is:

  $ gcc -v
  Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/specs
  Configured with: ../configure --prefix=/usr --mandir=/usr/share/man 
--infodir=/usr/share/info --enable-shared --enable-threads=posix 
--disable-checking --with-system-zlib --enable-__cxa_atexit 
--host=i386-redhat-linux
  Thread model: posix
  gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

which looks identical.  Here's the output from "uname -a" on my RH
9.0:

  $ uname -a
  Linux sherman.unidata.ucar.edu 2.4.20-8smp #1 SMP Thu Mar 13 17:45:54 EST 
2003 i686 i686 i386 GNU/Linux

So I still can't duplicate the problem, but maybe this will get you
closer to pointing me at it ...
