/*  File   : strlen.c
    Author : Richard A. O'Keefe. / Monty
	     Michael Widenius;	ifdef MC68000
    Updated: 1986-11-30
    Defines: strlen()

    strlen(s) returns the number of characters in s, that is, the number
    of non-NUL characters found before the closing NULEosCh.  Note: some
    non-standard C compilers for 32-bit machines take int to be 16 bits,
    either put up with short strings or change int  to	long  throughout
    this package.  Better yet, BOYCOTT such shoddy compilers.
    Beware: the asm version works only if strlen(s) < 65536.
