 ========
 
 The package uses a GNU style build system and requires a Unix style shell.
-On Windows it can be built with the MinGW toolchain and MSYS environment.
+
+Windows builds can be created natively with the MinGW-w64 toolchain and
+MSYS environment, or cross-compiled using a MinGW-w64 toolchain:
+
+  http://mingw-w64.sourceforge.net/
+
+The "old" MinGW from http://mingw.org/ is not supported.
 
 Run "./autogen.sh" to generate the build system, "./configure" to setup, then
 "make" to build the library and "make install" to install it.
