+/* Building under cygwin
+ *
+ * The approach I have taken with this port is to use primarily the UNIX 
+ * code base adding stuff that is MS-Windows specific. This works quite 
+ * well, and is in keeping with my perception of the cygwin philosophy.
+ * Note that if you make changes to this file you do NOT want to define 
+ * WINDOWSNT, I repeat - do not define this, it will break everything 
+ * horribly. What does get defined is HAVE_MS_WINDOWS, but this is 
+ * done by configure and only applies to the window system.
+ *
+ * When building make sure your HOME path is unix style - i.e. without
+ * a drive letter.
+ *
+ * once you have done this, configure and make.
+ *
+ * windows '95 - I haven't tested this under '95, it will probably
+ * build but I konw there are some limitations with cygwin under 95 so
+ * YMMV. I build with NT4 SP3.
