Even better than making readers chase a link is to just post your actual

Umm - that says you are using GnuWin32's make, not Cygwin's make.
Mismatching your build environment (by mixing two incompatible ports) is
a recipe for disaster.

If you are using Cygwin, then why not use Cygwin's pre-built m4 package
instead of trying to build it yourself? But if you are going to build
it, at least use Cygwin's make.  You'll probably need to fix your $PATH
to be something sane.

At any rate, your problem has nothing to do with upstream m4, and
everything to do with your environment, so this list is not going to be
the best source of help, compared to the Cygwin or GnuWin32 communities.
