lang/php* broken on NetBSD, patch supplied

[John Stalker <stalker%maths.tcd.ie@localhost>]

A recent commit to the main NetBSD tree, 
http://cvsweb.netbsd.org/bsdweb.cgi/src/include/stdio.h.diff?r1=1.79&r2=1.80&f=h&only_with_tag=MAIN&f=u
changed fpos_t, which causes main/streams/cast.c to fail to compile
on NetBSD in both the lang/php5 and lang/php53 ports.  It also breaks
some other packages, including print/cups, so it may be better to
fix this in the main tree rather than in pkgsrc, but the following
patch fixes both lang/php5 and lang/php53, and hopefully doesn't
break anything else:
