Update of /b/source/CVS/src/usr.bin/make
In directory sun-lamp.cs.berkeley.edu:/c/users/jtc/make

Modified Files:
	str.c suff.c 
Log Message:
Fixes from Christos Zoulas:
The following two patches fix a couple of problems with make(1)

1. Null Suffixes were not being copied, but they were being free'd
   This caused rules of the form:

   .c:
	${CC} ...

   to access invalid memory and potentially core dump..
   [That was always broken; I did not break that one :-)]

2. My recent fixes to parse ${VAR:%.foo=%.bar} handled the null string
   case incorrectly (${VAR:=.c} was broken).
