["Simon J. Gerraty" <sjg%netbsd.org@localhost>]

Module Name:    src
Committed By:   sjg
Date:           Sun Mar  6 00:02:15 UTC 2011

Modified Files:
        src/usr.bin/make: var.c
        src/usr.bin/make/unit-tests: Makefile cond1 test.exp
Added Files:
        src/usr.bin/make/unit-tests: misc sysv

Log Message:
Add unit tests to check that exists(some/dir/) works

Also fix handling of sysV substitutions when lhs and variable are empty.

Also that modifiers do not cause errors during conditional tests
when undefined variables should otherwise be ok.
Ie. .if defined(nosuch) && ${nosuch:Mx} != ""
