Sorry, I did not test the gcc-call I've provided in my last mail. I just
took out the important parts of the call as provided by the autotools...
guess I've missed something ;-)

Yes, that's expected ;-)

Hrm... I couldn't really find where exactly that comes from - that's
just a hell of nested macros. I could not find "fpsetreg" anywhere in
the perl sources though, so I expect it comes from some macro defined in
a system header which is then used by any of the Perl macros. The best
place to fix this would be wherever that last expanded macro is used
which is out of our scope. Anyway, as a (probably no-so-)temporary
workaround you can try the attached patch. I hope, the compiler is not
smart enough to still complain about it...

If anybody comes up with a better solution, I'd be quite happy! :-)

HTH,
Sebastian
