Do we still have this problem?  (is -frepo even useful on AIX?).

Yes.  And putting lots of system specific conditionals in tlink.c
isn't the right way to fix the problem :-)

I don't remember this, but it's quite likely it got lost in much
of the other aix/collect mail that went by a couple months ago.

Using regexps is probably the best solution.  Did you have a patch
for that or were you just suggesting it as a potential solution?

If we don't use regexps, then I would recommend we define some
sort of target macro to deal with this problem.
