28 | * Modified by Herbert 04/19/97: | |
29 | * - added new include file portab.h. | |
30 | * - added new private function fileloc_filenameForCpp() to handle | |
31 | * filenames belonging to "#line" statements for OS/2 and MSDOS. It | |
32 | * gets called by fileloc_lineMarker() and fileloc_previousLineMarker() | |
33 | * instead of fileloc_unparseFilename(). | |
