 * Copyright 1998-2000	Bertho A. Stultiens (BS)
 *
 * 21-May-2000 BS	- Fixed the ident requirement of resource names
 *			  which can be keywords.
 * 30-Apr-2000 BS	- Reintegration into the wine-tree
 * 11-Jan-2000 BS	- Very drastic cleanup because we don't have a
 *			  preprocessor in here anymore.
 * 02-Jan-2000 BS	- Removed the preprocessor code
 * 23-Dec-1999 BS	- Removed the copyright for Martin von Loewis.
 *			  There is really nothing left of his code in 
 *			  this parser.
 * 20-Jun-1998 BS	- Changed the filename conversion. Filenames are
 *			  case-sensitive inder *nix, but not under dos.
 *			  default behaviour is to convert to lower case.
 *			- All backslashes are converted to forward and
 *			  both single and double slash is recognized as
 *			  MS/Borland does.
 *			- Fixed a bug in 'yywf' case that prevented
 *			  double quoted names to be scanned propperly.
 *
 * 19-May-1998 BS	- Started to build a preprocessor.
 *			- Changed keyword processing completely to
 *			  table-lookups.
 *
 * 20-Apr-1998 BS	- Added ';' comment stripping
 *
 * 17-Apr-1998 BS	- Made the win32 keywords optional when compiling in
 *			  16bit mode
 *
 * 15-Apr-1998 BS	- Changed string handling to include escapes
 *			- Added unicode string handling (no codepage
 *			  translation though).
 *			- 'Borrowed' the main idea of string scanning from
 *			  the flex manual pages.
 *			- Added conditional handling of scanning depending
 *			  on the state of the parser. This was mainly required
 *			  to distinguish a file to load or raw data that
 *			  follows. MS's definition of filenames is rather
 *			  complex... It can be unquoted or double quoted. If
 *			  double quoted, then the '\\' char is not automatically
 *			  escaped according to Borland's rc compiler, but it
 *			  accepts both "\\path\\file.rc" and "\path\file.rc".
 *			  This makes life very hard! I go for the escaped
 *			  version, as this seems to be the documented way...
 *			- Single quoted strings are now parsed and converted
 *			  here.
 *			- Added comment stripping. The implementation is
 *			  'borrowed' from the flex manpages.
 *			- Rebuild string processing so that it may contain
 *			  escaped '\0'.
