Hello,

I have different win32 builds, which I do not think are sufficiently different in their --help. I'm not sure if they should do this either.


I thought something appended to the help output such as below would make it clear:

__
Path to binary: /usr/local/bin/make
Report bugs to <address@hidden>.
__


It would also be useful to others wishing to determine where the make they are running is actually on the filesystem.

The Cygwin version of GNU make is not supported by the FSF (this list).
If their --version output is not sufficiently distinct so that you can
tell it's not the "real" GNU make, that's something you should raise
with them: it's definitely a problem.

The UNIX version of GNU make does not do any parsing of PATH to find the
shell: the path the shell is included fully qualified in the SHELL
variable (default value is /bin/sh).

If you have a request for the Windows port you should ask on
address@hidden


I'm still not very clear on why you want the path to make.  It seems to
me that checking the version value should be able to tell you much more
easily whether you have the correct version or not.
