Attempts to compile Samba 3.0.4 using default options fails when using the IBM 
Visual Age Compiler (XLC) under AIX 5.1. The following error is reported 
(numerous times at various stages of the compilation):

      checking whether building shared libraries actually works... cc: 1501-218 
file shlib.po contains an incorrect file suffix

Resolution requires an edit of the file ./samba-3.0.4/source/configure and 
setting the PICSUFFIX variable in the AIX section (as is done for the Solaris 
section). The diff context output is as follows:
