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