Not sure what this is supposed to mean. I guess checking out the perlxs
manual as suggested might help.

This is interesting. Apparently the gcc 2.95.3 C compiler supports C99
variadic macros while the C++ compiler doesn't. Perl itself is C only, so
there was no problem with building it. You could try to undef the
HAS_C99_VARIADIC_MACROS macro in config.h. Maybe that will work.
At any rate, please file a bug report at HaikuPorts.

Ugh, that file has apparently not been installed. Not sure why -- I might
have missed adding it to some file listing. You can get it from the patch on
HaikuPorts (Scott sent the link to the port log); it's only a few lines
long. The file must probably live in .../BePC-haiku/CORE/haiku/.
Again, please file a bug report at HaikuPorts.

Nothing obvious wrong here. Run the above g++ line with "-E" instead of "-c"
and a different output file and check what this line is preprocessed to.

Same here.
