If the executable hasn't been stripped, dump -tv (to look at the
regular symbol table) will show you .file entries placed by
the xlc/xlC compilers. This information includes version number,
although not necessarily more detail than version/release.

There are so few compilers available for AIX that you can
usually figure out if it was the XL compilers (via
strings and dump) or gcc/g++ (via dump -Hv and looking at the
dependent modules).

Mostly, it's about derivation heuristics.
