thanks. old habits die hard. i'll read the current documentation and
the standard carefully before my next abuse of the compiler, which will
be a monthly event. :)

indeed, and i don't know if gcc should necessarily try to do this sort
of analysis. unfortunately no lint i have access to (including the quite
superior sun lint) would complain. lclint sort of does, but it doesn't
get it right:

boyd.c:3:14: Name strcpy is reserved for future ANSI library extensions. 
    Functions that begin with "str" and a lowercase letter may be added to
    <stdlib.h> or <string.h>. (See ANSI, Section 4.13.7)
  External name is reserved for system in ANSI standard. (-ansireserved will
  suppress message)

i did not try any harder.
