+Building on Windows
+===================
+
+QPDF is known to build and pass its test suite with mingw (gcc 4.4.0)
+and Microsoft Visual C++ .NET 2008 Express.  In both cases, cygwin is
+required to run the test suite.  Either cygwin or MSYS is required to
+build as well in order to get make and other related tools.  The MSVC
+build has only been tested under cygwin.  The mingw build requires
+MSYS and will probably not work with cygwin.
+
+For details on how to build under Windows, see README.windows.
+
+
+Additional Notes on Build
+=========================
+
+QPDF's build system, inspired by abuild (http://www.abuild.org), can
+optionally use its own built-in rules rather than using libtool and
+obeying the compiler specified with configure.  This can be enabled by
+passing --with-buildrules=buildrules where buildrules corresponds to
+one of the .mk files (other than rules.mk) in the make directory.
+This should never be necessary on a UNIX system, but may be necessary
+on a Windows system.  See README.windows for details.  There is a
+gcc-linux.mk file enable "gcc-linux" build rules, but it is intended
+to help test the build system; Linux users should build with the
+"libtools" rules, which are enabled by default.
 The QPDF package provides some executables and a software library.  A
 user's manual can be found in the "doc" directory.  The docbook
