11db3170 | 32 | ** Modified by Herbert 08/19/97: |

34 | ** - fixed weird bug with lookup of tmp files (OS/2 and MSDOS only). | |

ac0860d8 | 36 | /* |
11db3170 | 37 | ** Modified by Mike Smith |
38 | ** Corrected missing 'line' in scanf() calls in handleSpecial(). | |
39 | ** Without this, I get an error when LCLint hits a '#line' directive | |
40 | ** in the pre-pre-processed source files. For safety, I have made these | |
41 | ** conditional on OS2 and MSDOS because I don't understand why noone else | |
42 | ** has seen this problem. | |
43 | ** | |
44 | ** Modified by Mike Smith, 4th June 1997 | |
45 | ** Finally resolved the #line problem. The scanf() calls have been fixed to | |
46 | ** allow the following #line forms:- | |
47 | ** | |
48 | ** #line 123 "filename" | |
49 | ** #line 123 | |
50 | ** # 123 "filename" | |
51 | ** # 123 | |
52 | ** | |
53 | ** The last two are generated by the GNU pre-processor, apparently | |
