	The version of GCC you are using is not based on an FSF release,
so this is the wrong forum for asking question.

	This is all user error.  AIX shared libraries do not use the ".so"
file extension by default, so the AIX linker will not notice the libfoo.so
file.  One can enable Solaris-style linking behavior with the AIX linker
-brtl flag that enables both ".so" file extension for shared libraries and
runtime linking semantics.  The GCC commandline method for passing options
to the linker is to prepend the option with "-Wl," in other words
"-Wl,-brtl".  The "-b" option has its own meaning to GCC.
