Okay, I really don't understand this.  Line 2069 in cc.c is dXSARGS, which
should be a very standard Perl thing.  I don't see anything in the
5.005_02 header files that should be causing this problem.  Line 528 of
proto.h is:

        VIRTUAL char*   sv_2pv _((SV* sv, STRLEN* lp));

which indicates the mismatch has something to do with SvPV() and that
somewhere STRLEN is being declared as an int rather than an unsigned int,
but I have no idea where that could be....

Hurm.  Oh, joy.  STRLEN is MEM_SIZE, which is defined to be Size_t, which
in turn is defined in Perl's config.h.  I wonder if we're getting another
include file conflict.  It's using "" to include config.h rather than <>,
so it should pick up config.h from Perl's include directory rather than
ours, though.  But that reminds me that if I reorder include directives to
put Perl's include directory first, that's going to break our config.h.
So I can't keep that change.  Feh.

I don't have Perl compiled with threading.
