For dynamic loading to work on AIX (and VMS) we need to provide a list
of symbols to be exported. This is done by the script F<perl_exp.SH>,

On the other hand, one of the goals of Perl5 is to make it easy to

That is, we don't want perl's global variables to conflict with
those in the other application library. Although this work is still
in progress, the way it is currently done is via the F<embed.h> file.

As long as the prototypes in actual use don't vary that much, this is
