+A Word on compiling under Cygwin with gcc\r
+-----------------------------------------\r
+\r
+Cygwin is a POSIX style operating environment for Windows. It is possible to\r
+compile the EDK 2 using gcc and cygwin. There are a few extra steps necessary\r
+to make this happen. There is a JNI (Java Native Interface) library in the\r
+Tools.  In order to compile this under Cygwin, the 'linux' java headers must be\r
+installed to the $JAVA_HOME dir on the windows system. To accomplish this, you\r
+must install the JDK on a linux system, and then copy\r
+linux:$JAVA_HOME/include/linux/ to windows:$JAVA_HOME/include. These are really\r
+typedefs needed by gcc.\r
+\r
+Compiling under cygwin is slow, because the underlying file accesses are slow\r
+in cygwin. For this reason, we do not encourage the use of cygwin. A true unix\r
+system will be a superior choice for those wishing to compile with gcc.\r
+\r
+Make sure that you select the e2fsprogs development package when you install\r
+cygwin. It is necessary for the GenFvImage tool.\r
