With Cygwin, the same guidelines as for Posix (Unix and GNU/Linux)
systems should work (see README.cvs).  However, the result will be a
Cygwin build of Make, not a native Windows port.  The Cygwin build is
recommended for use only with Cygwin tools, and MinGW/MSVC build is
recommended for use only with native Windows development tools.

With MinGW and MSVC, running build_w32.bat should work if you add the
line that produces config.h from config.h.W32.template.  But make sure
you edit template strings such as %VERSION% into something suitable
before you run the compiler.

Sorry, I missed that.  However, as Paul points out, your change is not
correct.  Can you please suggest a change that doesn't try to modify
const variables?
