These are the maximum number of characters, including null terminator, for
a filename with path, drive, etc.  Values from Borland C 3.0 are:
#define MAXPATH   80
#define MAXDRIVE  3
#define MAXDIR    66
#define MAXFILE   9
#define MAXEXT    5

(Your names are slightly different because they are the Microsoft equivalents.
Borland defines their constants in DIR.H, and also defines MSC's in STDLIB.H)
