- * Manuel Novoa III       Dec 2000
- *
- * Converted to use my new (un)signed long (long) to string routines, which
- * are smaller than the previous functions and don't require static buffers.
- * Removed dependence on strcat in the process.
- *
- * Also appended a test routine ( -DCHECK_BUF ) to allow a quick check
- * on the buffer length when the sys_errorlist is modified.
- *
- * Added the option WANT_ERRORLIST for low-memory applications to omit the
- * error message strings and only output the error number.
- *
- * Manuel Novoa III       Feb 2002
- *
- * Change to _int10tostr and fix a bug in end-of-buf arg.
- *
- * Erik Andersen          June 2002
- *
- * Added strerror_r (per SuSv3 which differs from glibc) and adapted
- * strerror to match.
