Make: Issue with $(MAKE) in make includes, when make is not on the default path

Hi,

Just found a possible issue with Cygwin:
If cygwin is not on the default path, and make is started by specyfing 
the path to it (e.g., c:\cygwin64\bin\make), $(MAKE) works in the 
top-level makefile, but it does not work in make includes.
To reproduce the issue, use these files:

makefile:
$(info $(shell $(MAKE) --version))
include test.mak

test.mak:
$(info $(shell $(MAKE) --version))

Make sure that Cygwin is not on the default path, e.g. type *path ;* to 
erase the default path entirely.
Then start make by specifying the path to it: c:\cygwin64\bin\make

The first $(MAKE) call works, the second one does not.
If make is on the default path, both work.

Best regards,

Hi Ferenc,

I doubt this should be considered a specific Cygwin bug or a bug at all

This works as expected when calling /bin/make or C:/cygwin64/bin/make ;
the problem is the backslash notation.
