Shared libs are obviously not their strong side :-)
Basically we are very happy with their RS6000's and AIX though.

they don't matter

gcc and not xlc :-) actually xlc produces faster code, but I don't think that makes a
noticeable difference.

Always use the compiler for linking instead of ld:
gcc -Wl,-H512 -Wl,-bM:SRE -o $@ $< -L ${PGLIBDIR} -bI:/usr/local/pgsql/lib/postgres.imp \
-bexpall -bnoentry

You are not allowed to leave anything unresolved, thus do not use -G, or you won't notice
unresolved externals (-G includes -berok which you don't want at all).
