-
- DESCRIPTION
-
- Given pointers to pointers to two partial symbol table entries,
- compare them by name and return -N, 0, or +N (ala strcmp).
- Typically used by sorting routines like qsort().
-
- NOTES
-
- Does direct compare of first two characters before punting
- and passing to strcmp for longer compares. Note that the
- original version had a bug whereby two null strings or two
- identically named one character strings would return the
- comparison of memory following the null byte.
