CVS commit: src/usr.bin/make

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

Module Name:    src
Committed By:   sjg
Date:           Sun Jun  6 01:13:12 UTC 2010

Modified Files:
        src/usr.bin/make: make.1 var.c

Log Message:
Add .export-env which tells make to export a variable to the environment
but not to track it - as is done for .export
This allows the variable to be updated without affecting what was put
into the environment.
Older versions of make will simply treat this as .export
