I believe this is only if __ANSI_CPP_ is defined...  So this should not
be the problem.  Any ANSI CPP should replace fxCAT(string1, string2)
with string1string2.

Hm.. Yes, indeed.  I haven't been able to chase down the problem any
more (it seems to work on all the compilers I've tried).

Can someone who is having the problem send us the "preprocessor"
output?  I'm not sure what the options are for AIX CC, but for gcc,
just put a "-E" on the line, and it will spit it out instead of compile
it.  I would be interested in seeing it.

Yup.
