Last change on this file since 22016 was 21929, checked in by dmik, 14 years ago

Replace tmpnam() with tempnam().

The former in EMX returns paths relative to the current
directory while it should be relative to %TMP%.

r21928 also does that.

3 * Copyright Martin von Loewis, 1994
4 * Copyrignt 1998 Bertho A. Stultiens (BS)
5 *
6 * 30-Apr-2000 BS - Integrated a new preprocessor (-E and -N)
7 * 20-Jun-1998 BS - Added -L option to prevent case conversion
8 * of embedded filenames.
9 *
10 * 08-Jun-1998 BS - Added -A option to generate autoregister code
11 * for winelib operation.
12 *
13 * 21-May-1998 BS - Removed the CPP option. Its internal now.
14 * - Added implementations for defines and includes
15 * on the commandline.
16 *
17 * 30-Apr-1998 BS - The options now contain nearly the entire alphabet.
18 * Seems to be a sign for too much freedom. I implemeted
19 * most of them as a user choice possibility for things
20 * that I do not know what to put there by default.
21 * - -l and -L options are now known as -t and -T.
22 *
23 * 23-Apr-1998 BS - Finally gave up on backward compatibility on the
24 * commandline (after a blessing from the newsgroup).
25 * So, I changed the lot.
26 *
27 * 17-Apr-1998 BS - Added many new command-line options but took care
28 * that it would not break old scripts (sigh).
29 *
30 * 16-Apr-1998 BS - There is not much left of the original source...
31 * I had to rewrite most of it because the parser
32 * changed completely with all the types etc..
