The new POSIX standard is now official (IEEE Std 1003.1-2001), and it
has removed support for an obsolete utility option that m4 uses.
Basically, the new POSIX has removed digit-string options (e.g., "tail
-1") and options beginning with "+" (e.g., "sort +1"). I'm using an
experimental environment that insists on the new standard, so I tend
to run into these problems before other people do.
Here is a proposed patch for GNU m4.

* examples/mktests.sh: Use `sed q', rather than `head -1',
as POSIX 1003.1-2001 no longer allows `head -1'.
