 To build ppremake on Unix (or Windows Cygwin) using autoconf, follow

-build ppremake if you want to build a version of ppremake that can
-correctly decode Cygwin-style pathnames into Windows-style pathnames.
+If you are on Windows, note that you may build ppremake either using
+or without using Cygwin.  This document describes how to build it with
+Cygwin; if you want to build it without Cygwin just use the provided

+Panda), you must also use Cygwin to build ppremake, since otherwise
+ppremake will not be able to correctly decode Cygwin-style pathnames
