Attempting download - bombed out last night.  Unfortunately, it will be a pain 
to use gcc-295 'cause of work commitments - I'm kind of stuck with the GNU Pro 
tools.

added set -x to mknumeric_limits.  [this also touched the file causing it to 
try to build limitsMEMBERS.cc - why is $(generated_headers) dependent on it?]

So there is a compatibility probem with the compiler/libs I'm using.  Any 
thoughts?
