CVS commit: basesrc

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

Module Name:    basesrc
Committed By:   sjg
Date:           Sun Jun 10 02:31:01 UTC 2001

Modified Files:
        basesrc/usr.bin/make: main.c make.1 parse.c var.c

Log Message:
Simplify the exporting of VAR_CMD's via MAKEFLAGS.
We now just list the names of such variables in .MAKEOVERRIDES.
When we come to export MAKEFLAGS we quote the value of each exported variable
using :Q, using: ${.MAKEOVERRIDES:O:u:@v@$v=${$v:Q}@}
The :O:u suppresses duplicate names.
Also modifed Parse_DoVar to re-export MAKEFLAGS whenever .MAKEOVERRIDES
is assigned to so .MAKEOVERRIDES+= PATH will export PATH=${PATH:Q}
to the environment, while .MAKEOVERRIDES= will disable export of VAR_CMD's.
