NetBSD pc2 1.6.2 NetBSD 1.6.2 (GENERIC) #0: Tue Feb 10 21:53:10 UTC 2004

>Description:
The NetBSD 1.6 rpcgen does fail when the environment variable CPP
is set to "cpp" -- it need it to be set to the full path.
mk/platform/NetBSD.mk does ensure that it is set to the full path,
but the recent changes to the infrastructure makes this value
be overridden at a later time by (at least) the compiler/gcc.mk
and the wrapper stuff.

This makes e.g. the net/sharity-light package fail on
NetBSD/1386-1.6.2 due to:
rpcgen -c nfs_prot.x |  sed 's;^#include ".*/nfs_prot.h"$;#include 
"nfs_prot.h";' >nfs_prot_xdr.c
cannot find any C preprocessor (cpp)

(see ftp://ftp.netbsd.org/pub/NetBSD/misc/kristerw/pkgstat/i386-1.6.2 for
error logs)
