>Description:
When trying to build NetBSD-9 release on a NetBSD-5.2 system using sources
from the netbsd-9 branch, nbmake core dumps when realpath is called from
usr.bin/make/parse.c.  It appears the changes sjg made in Revision 1.231 of
parse.c are the culprit.  Using versions of parse.c older than 1.231 run
without trouble on NetBSD-5.2.
	
>How-To-Repeat:
	
Download the src-90 source tree on a NetBSD-5.2 system.
Clear your obj directory.
Then run:

./build.sh -m amd64 -D /var/tmp/netbsd-90-64 -O /usr/local/netbsd/obj-64 -j 4 release
>Fix:
Figure out why realpath is seg faulting with the pointers given it by
parse.c as added in parse.c, 1.231.
