+CYGWIN Notes\r
+\r
+You should setup cygwin to use binmode on all mounts. When you initially\r
+install cygwin it gives you the choice of Unix file mode (recommended) or DOS\r
+file mode. Unix mode will cause all the cygwin directories to be mounted in\r
+binmode, while DOS will mount the dirs in textmode. Here is an example of a\r
+cygwin install where the dirs are (properly) mounted in binmode.\r
+\r
+C:\cygwin\bin on /usr/bin type user (binmode)\r
+C:\cygwin\lib on /usr/lib type user (binmode)\r
+c:\workspace on /workspace type system (binmode)\r
+C:\cygwin on / type user (binmode)\r
+\r
+If you use textmode, it is likely that the build will fail in a way that is\r
+hard to debug.\r
+\r
+Cygwin is pretty slow, so it is not recommended for large builds.\r
