Gisle Vanem's djgpp/MS-DOS updates

packages/DOS/README

@@ -2,3 +2,10 @@ Gisle Vanem made curl build fine on DOS (and MingW) with djgpp, OpenSSL and his
 Watt-32 stack.
 
 'make djgpp' in the root curl dir should build it fine.
+
+Note 1: djgpp 2.04 beta has a sscanf() bug so the URL parsing isn't
+        done proberly. Use djgpp 2.03 until they fix it.
+
+Note 2: Compile Watt-32 (and OpenSSL) with the same version of djgpp.
+        Otherwise things go wrong because things like FS-extensions and
+        errnos have been changed between releases.
