bash link fails on AIX

[Perry Smith]

I can not use bugbash so I am hoping I include all the information  
that is needed.

I'm compiling bash-3.1 using IBM's compiler.  I'm on AIX 5.3.  I did  
just the normal ./configure followed by make.  Everything is fine  
until the final link.  It fails because it can not find isnan.

To work around the problem I just captured the stdout of make into a  
file, edited the file and added "-lm" at the end to get IBM's math  
library.  It now links and it seems to execute fine.

Hope this helps,
Perry
