Perl-5.8.0's Configure contains an appropriate va_copy test, and
perl-5.8.0's handy.h contains an appropriate macro to use. (Earlier
perl's didn't have the test, so we'll have to copy the test, not just use
the Config.pm result, but that's no big deal.)
Perl-5.8.0's PerlIO system does sundry tricks with varargs, and they work,
so there's an existing working basis.
The bigger issue is that Brent's clever way of using the same core for
both direct vararags and pmc types relies on using data.obj as either a
va_list or a pmc. I'm not sure if that'll work on PPC (or he may have to
use a union or some such). Direct testing on PPC is the best bet to
answer such questions.
