PERL_VER = `perl -e 'print $['`

I assume you mean:

PERL_VER = `$^X -e 'print $]'`
as you cannot be sure the Makefile.PL is called by "perl". And note it should be $] rather than $[

Actually, if I would have to resort to that, it would probably be easier to not define a macro for 5.6.x, and define a macro with the the PROTOTYPE: string for all other versions.


While investigating something about $[, I realized there was an error in this node. So I changed $[ to $] where appropriate and added a comment.

    That's exactly what I meant ;) I wonder if the xsubpp maintainer (is there one?) can be convinced to allow a pre-processing option, similar to 'perl -P'.
      Here is a patch which adds preliminary pre-processor support to xsubpp. There's a few caveats. #line will now be incorrect, since the #includes now occur BEFORE xsubpp gets to them (I wonder if there's a way to disable those directives). As soon as I get better testing done, I'll send this in to whoever is supposed to see it. To invoke, use xsubpp -preprocess blah
