Well, Perl_ and PERL_ won't work, since that's relying on case-sensitivity 
in the various linkers, which is a Bad Thing. Having Perl_ and PL_ to 
separate code and data is in there mainly to make separating things 
programmatically easier. We could, I suppose, make everything Perl_ and 
have a config file somewhere with the type (data/code/whatever) indicated.

That's probably the best thing--since we're exporting only a reasonably few 
things, and only explicitly, it ought to be OK.
