CVS commit: basesrc

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

Module Name:    basesrc
Committed By:   sjg
Date:           Sat Jun  9 05:22:48 UTC 2001

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

Log Message:
Modify handling of command line variable assignments and their exporting
via MAKEFLAGS.  Instead of appending them directly to .MAKEFLAGS, put
them in .MAKEOVERRIDES (and ensure they are quoted).  This is now done
in Var_Set when it exports VAR_CMD's.
Use ExportMAKEFLAGS() to export MAKEFLAGS, using the combined content
of .MAKEFLAGS and .MAKEOVERRIDES (with duplicate supression).
If .MAKEFLAGS is assigned to in a Makefile, ExportMAKEFLAGS is called again.
This allows a line like:
.MAKEOVERRIDES=
to effectively stop the exporting of the command line vars in MAKEFLAGS.
