Hi:

I have a problem with gmake related to the MAKE_MODE environment variable.
We have a large gmake system that is using and relies on MAKE_MODE=UNIX.
A new subsystem calls gmake from this but it wants MAKE_MODE=DOS so
that no backslashes are lost. Basically what we do is:

Makefile:
---------------------------------------------------------------------------
# assume this makefile is called with MAKE_MODE=unix

SHELL=/bin/sh

all:
 echo $(MAKE_MODE)
 ./batch.bat
----------------------------------------------------------------------------

Batch.bat:
----------------------------------------------------------------------------
set MAKE_MODE=dos
gmake -f Makefile2
----------------------------------------------------------------------------

Makefile2:
----------------------------------------------------------------------------
all:
 command.com /c echo $(MAKE_MODE)
 command.com /c echo c:\windows
----------------------------------------------------------------------------

The output of running gmake shows:


F:\visbuild\problem>gmake
echo unix
unix
./batch.bat

F:\visbuild\problem>
F:\visbuild\problem>set MAKE_MODE=dos

F:\visbuild\problem>gmake -f Makefile2
command.com /c echo dos
dos
command.com /c echo c:\windows
c:windows     <-------------------- !!!!!!!!!!!

F:\visbuild\problem>


I.e. although MAKE_MODE is set to DOS the second invocation of gmake 
does not treat a backslash properly. 


Interestingly if I call BATCH.BAT directly from the command line I get:

F:\visbuild\problem>batch
F:\visbuild\problem>set MAKE_MODE=dos

F:\visbuild\problem>gmake -f Makefile2
command.com /c echo dos
dos
command.com /c echo c:\windows
c:\windows  <-------------------- !!!!!!!!!!!

F:\visbuild\problem>


Is there another environment variable that the second invocation inherits
from the first that needs to be reset to make sure that a \ is not considered
as an escape character?


Thanks, Erwin
