Besides, I'm not convinced the performance loss of -mminimal-toc would
be smaller than that of -bbigtoc, so I went with the latter for now.
Tested on AIX 4.1.  Ok to install?

I just created gdb/390 to track this but then noticed that Peter is an 
AIX maintainer.  Was that an OK?

(Oh and don't forget, no one maintains configure.in everyone gets to 
change it, but only if they dare :-)

enjoy,
Andrew

If it was, I'll be more than happy to install the patch in GDB
mainline and 5.2 branch.  Just let me know.

Boldly changing configure.in like no man did before :-)

As you are much more experienced with autoconf than me, yes, it's an OK
from me.
