<linux/string.h> includes <asm/string.h> which has the the inline
functions for m68k.
But there are no warnings in the log for use of these functions
without declarations. So if <linux/string.h> is not included
already (indirectly), where are they declared? I don't believe
the built-in string functions are automatically declared.
We get into the habit of living before acquiring the habit of thinking.
