 INSTALLATION ON THE DOS PLATFORM WITH DJGPP
 -------------------------------------------

 OpenSSL has been ported to DJGPP, a Unix look-alike 32-bit run-time
 environment for 16-bit DOS, but only with long filename support.
 If you wish to compile on native DOS with 8+3 filenames, you will
 have to tweak the installation yourself, including renaming files
 with illegal or duplicate names.

 You should have a full DJGPP environment installed, including the
 latest versions of DJGPP, GCC, BINUTILS, BASH, etc. This package
 requires that PERL and the PERL module Text::Template also be
 installed (see NOTES.PERL).

 All of these can be obtained from the usual DJGPP mirror sites or
 directly at "http://www.delorie.com/pub/djgpp". For help on which
 files to download, see the DJGPP "ZIP PICKER" page at
 "http://www.delorie.com/djgpp/zip-picker.html". You also need to have
 the WATT-32 networking package installed before you try to compile
 OpenSSL. This can be obtained from "http://www.watt-32.net/".
 The Makefile assumes that the WATT-32 code is in the directory
 specified by the environment variable WATT_ROOT. If you have watt-32
 in directory "watt32" under your main DJGPP directory, specify
 WATT_ROOT="/dev/env/DJDIR/watt32".

 To compile OpenSSL, start your BASH shell, then configure for DJGPP by
 running "./Configure" with appropriate arguments:

	./Configure no-threads --prefix=/dev/env/DJDIR DJGPP

 And finally fire up "make". You may run out of DPMI selectors when
 running in a DOS box under Windows. If so, just close the BASH
 shell, go back to Windows, and restart BASH. Then run "make" again.

 Quoting FAQ:

  "Cryptographic software needs a source of unpredictable data to work
   correctly.  Many open source operating systems provide a "randomness
   device" (/dev/urandom or /dev/random) that serves this purpose."

 As of version 0.9.7f DJGPP port checks upon /dev/urandom$ for a 3rd
 party "randomness" DOS driver. One such driver, NOISE.SYS, can be
 obtained from "http://www.rahul.net/dkaufman/index.html".
