 HOW TO BUILD PANDA ON A WINDOWS SYSTEM, WITHOUT CYGWIN
 
+Note: although Panda can be built without Cygwin, for the moment we
+have dropped support for the Microsoft nmake program (which is not
+really supported by Microsoft either).  Thus, even though you do not
+need to have all of Cygwin installed, you will need to have at least
+GNU make.  This program is available from Cygwin (make.exe); you can
+copy this program from someone who has installed Cygwin, or you can go
+to www.cygwin.com and try to install just this one program.  You will
+also need the support DLL, cygwin1.dll.
+
 You will need a directory for holding the installed Panda.  This can
 be anywhere you like; in this example we'll assume you use a directory
 called "panda3d" on the root of the C drive.
 
   md c:\panda3d
 
-Panda3D includes a pre-compiled ppremake.exe, but not the cygwin DLL.
-Since ppremake is a Cygwin program (even though the rest of Panda is
-not), you will need the DLL in order to run ppremake.

-The cygwin1.dll should be available at http://www.cygwin.com
+You will first need to build a copy of ppremake.exe.  There is a
+Microsoft project file in the ppremake directory that will build this.
+Once it is built, copy it to the Panda bin directory (which you will
+have to make yourself).  This will be a directory called "bin" below
+the root of the installed directory you created above; for instance,
+c:\panda3d\bin.
 
 Make sure the Panda bin and lib directories are on your path, and set
 a few environment variables for building.  We suggest creating a file
