We still need a test case.  You can put all sorts of words in the report
but, from what you are explaining, it sounds like you should be able to
come up with a makefile which easily demonstrates the problem.

Then, we need to know *how*you*are*running*make*.

You don't have to go into exhaustive detail about how mozilla works.
You just need a (probably) three line makefile and a copy of the make
command line and, if you are using it, description of the MAKE_MODE
environment variable setting.

I am not trying to be difficult.  I have tried to construct my own test
case and, AFAICT, it works fine.

I run it like thist:

make --win32 -f mkfile

mkfile contains:

VPATH=c:/tmp
all: remount.bat
	echo $?

remount.bat exists in c:/tmp.

I do not have the MAKE_MODE environment variable set.  It works the
same way if I set MAKE_MODE=win.
