20 /* Building under cygwin
21 *
22 * The approach I have taken with this port is to use primarily the
23 * UNIX code base adding stuff that is MS-Windows specific. This works
24 * quite well, and is in keeping with my perception of the cygwin
25 * philosophy. Note that if you make changes to this file you do NOT
26 * want to define WIN32_NATIVE (formerly "WINDOWSNT"), I repeat - do
27 * not define this, it will break everything horribly. What does get
28 * defined is HAVE_MS_WINDOWS, but this is done by configure and only
29 * applies to the window system.
30 *
31 * When building make sure your HOME path is unix style - i.e. without
32 * a drive letter.
33 *
34 * once you have done this, configure and make.
35 *
36 * windows '95 - I haven't tested this under '95, it will probably
37 * build but I know there are some limitations with cygwin under 95 so
38 * YMMV. I build with NT4 SP3.
