/* 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.
 *
 * The important thing about building is that it is done on a binary
 * mounted filesystem. i.e. something mounted like: mount -b c:
 * /binary. If you do not do this then compilation of el files will
 * produce garbage.  Make sure you have installed cygwin32 b18 +
 * patched dll (which can be found at http://www.lexa.ru/sos or on my
 * home page. Alternatively when b19 comes out the patched dll will be
 * unnecessary. Also make sure your HOME path is unix style -
 * i.e. without a drive letter.
 *
 * once you have done this, configure and make. The
 * undump phase will fail but that is to be expected. To run you need
 * to set EMACSLOADPATH, EMACSDOC, EMACSDATA etc appropriately and then do:
 * temacs -batch -l loadup.el run-temacs
 * 
 * What I want to do
 *
 * the fileio stuff merely uses the unix system calls this means that
 * the mount type of your fs will determine how files are edited. This
 * is fine except in the instance that you want to convert one to the
 * other. In this instance I would like to bring the buffer_file_type
 * code into the picture without all the other windows-nt cruft.
 *
 * Also the undumped version should be able to do path guessing, I
 * don't know why it doesn't currently.
 *
 * Ideally a dumped version would be done but I'm not sure I am up to
 * the task.
