CVS commit: src/usr.bin/make

[David Laight <dsl%netbsd.org@localhost>]

Module Name:    src
Committed By:   dsl
Date:           Sun Dec 21 10:44:10 UTC 2008

Modified Files:
        src/usr.bin/make: var.c

Log Message:
Don't allow $) $} $: or $$ as variable expansions, they confuse other
  parts of make that try to scan through variable expansions.
  (given the make syntax that is all rather doomed anyway!)
Move the check for $\0 to a place where it will be detected - otherwise
  the parser will run off the input buffer!
