19 * History:
20 * 21-May-2000 BS - Fixed the ident requirement of resource names
21 * which can be keywords.
22 * 30-Apr-2000 BS - Reintegration into the wine-tree
23 * 11-Jan-2000 BS - Very drastic cleanup because we don't have a
24 * preprocessor in here anymore.
25 * 02-Jan-2000 BS - Removed the preprocessor code
26 * 23-Dec-1999 BS - Removed the copyright for Martin von Loewis.
27 * There is really nothing left of his code in
28 * this parser.
29 * 20-Jun-1998 BS - Changed the filename conversion. Filenames are
30 * case-sensitive inder *nix, but not under dos.
31 * default behaviour is to convert to lower case.
32 * - All backslashes are converted to forward and
33 * both single and double slash is recognized as
34 * MS/Borland does.
35 * - Fixed a bug in 'yywf' case that prevented
36 * double quoted names to be scanned propperly.
37 *
38 * 19-May-1998 BS - Started to build a preprocessor.
39 * - Changed keyword processing completely to
40 * table-lookups.
41 *
42 * 20-Apr-1998 BS - Added ';' comment stripping
43 *
44 * 17-Apr-1998 BS - Made the win32 keywords optional when compiling in
45 * 16bit mode
46 *
47 * 15-Apr-1998 BS - Changed string handling to include escapes
48 * - Added unicode string handling (no codepage
49 * translation though).
50 * - 'Borrowed' the main idea of string scanning from
51 * the flex manual pages.
52 * - Added conditional handling of scanning depending
53 * on the state of the parser. This was mainly required
54 * to distinguish a file to load or raw data that
55 * follows. MS's definition of filenames is rather
56 * complex... It can be unquoted or double quoted. If
57 * double quoted, then the '\\' char is not automatically
58 * escaped according to Borland's rc compiler, but it
59 * accepts both "\\path\\file.rc" and "\path\file.rc".
60 * This makes life very hard! I go for the escaped
61 * version, as this seems to be the documented way...
62 * - Single quoted strings are now parsed and converted
63 * here.
64 * - Added comment stripping. The implementation is
65 * 'borrowed' from the flex manpages.
66 * - Rebuild string processing so that it may contain
67 * escaped '\0'.
