CVS commit: src/usr.bin/make

["Christos Zoulas" <christos%netbsd.org@localhost>]

Module Name:    src
Committed By:   christos
Date:           Tue Jul 16 14:00:53 UTC 2013

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

Log Message:
More gmake compatibility:
1. add -w flag to print Entering and Leaving directory name the the beginning
   and the end of processing.
2. export MAKELEVEL=$((MAKELEVEL + 1)) only in the child environment.
3. when printing error messages, prefix them with the program name [$MAKELEVEL]
   for $MAKELEVEL > 0
4. if $MAKEFLAGS consists only of letters assume it is a set of flags (as
   allowed by posix), convert them to -f -l -a -g -s, so that they get parsed
   properly.
With those fixes gmake -> bmake -> gmake -> bmake etc. works as expected.
