Re: [6465] small fixes for XSParagraph

[Karl Berry]

    different variable is probably what is needed, maybe "PERLCFLAGS" or
    "XSCFLAGS" or "EXTENSIONCFLAGS".

Ok, if a user can set another variable, let's say PERLCFLAGS, to control
the flags for the xs compilation, that makes sense.  For instance, a
user should be able to say CFLAGS=-g PERLCFLAGS=-g (or whatever) to
eliminate optimization.

I think PERL or XS would be a better name than EXTENSION.  I'd go for
PERL.  One can theoretically imagine a program using multiple extension
languages, and then the language name would seem clearest. (PERL,
PYTHON, GUILE, ...)  -k
