CVS commit: basesrc/usr.bin/make

[Todd Vierling <tv%netbsd.org@localhost>]

Module Name:    basesrc
Committed By:   tv

Modified Files:
        basesrc/usr.bin/make: suff.c

Log Message:
Fix a very old and annoying bug: Adding suffixes to sufflist wasn't setting
a refCount of 1 to indicate its presence on sufflist.  Hence suffixes were
being removed by Suff_EndTransform() and being freed before all the
referential links were removed.  This resulted in a malloc warning on 1.5.x:
  make in free(): warning: chunk is already free.

This could be reproduced with the following simple Makefile passed to
"make -r":
=====
.SUFFIXES: .l .c
.l.c:
foo:
