[ID 19991118.009] small problem

I was in:
http://www.perl.com/CPAN-local/doc/manual/html/pod/perlembed.html#Compiling_your_C_program
and I had trouble compiling the string.c example. Specifically the
line:
printf("a = %s\n", SvPV(perl_get_sv("a", FALSE), PL_na));
was the trouble maker. PL_na was undefined. I did, however, find:
/opt/perl5/lib/CORE/perl.h:EXT STRLEN na; /* for use in
SvPV when length is Not Applicable */
So I changed the line to the following and it compiles/runs just fine.
printf("a = %s\n", SvPV(perl_get_sv("a", FALSE), na));

I know this isn't a "perl" or "document" bug but I think ironing out
examples helps,
especially for a novice user such as myself.
Thanks for making these examples available!
