The doc in pkgsrc guide seems wrong,
I think using "CPP= /usr/ccs/lib/cpp' give false result in configure,
at least for emacs.

/usr/ccs/lib/cpp don't have predefine symbol about arch, specialy
for 64bits.

I suggest to set CPP in mk.conf like that:

CPP= ${CC} -E

and move the recommanded line in section 3.3.7.3 (building 64bits)


Thanks,
