38 | * Herbert 04/1997: | |
39 | * - Added conditional stuff (macros OS2 and MSDOS) to make names of temporary | |
40 | * files under Windows or OS/2 not larger than 8+3 characters to avoid | |
41 | * trouble with FAT file systems or Novell Netware volumes. | |
42 | * - Added include of new header file portab.h containing OS dependent stuff. | |
43 | * - Changed occurance of '/' as path delimiter to a macro. | |
44 | * - Added conditional stuff (#define and #include) for IBM's compiler. | |
