20 | * Modified by Herbert 08/19/97: | |
21 | * - added #include for IBM's OS/2 compiler. | |
22 | * - fixed weird bug with lookup of tmp files (OS/2 and MSDOS only). | |

25 | /* | |
26 | * Modified by Mike Smith | |
27 | * Corrected missing 'line' in scanf() calls in handleSpecial(). | |
28 | * Without this, I get an error when LCLint hits a '#line' directive | |
29 | * in the pre-pre-processed source files. For safety, I have made these | |
30 | * conditional on OS2 and MSDOS because I don't understand why noone else | |
31 | * has seen this problem. | |
32 | * | |
33 | * Modified by Mike Smith, 4th June 1997 | |
34 | * Finally resolved the #line problem. The scanf() calls have been fixed to | |
35 | * allow the following #line forms:- | |
36 | * | |
37 | * #line 123 "filename" | |
38 | * #line 123 | |
39 | * # 123 "filename" | |
40 | * # 123 | |
41 | * | |
42 | * The last two are generated by the GNU pre-processor, apparently | |
