/**		errno.c			**/

/** This routine maps error numbers to error names and error messages.
    These are all directly ripped out of the include file errno.h, and
    are HOPEFULLY standardized across the different breeds of Unix!!

    If (alas) yours are different, you should be able to use awk to
    mangle your errno.h file quite simply...
