[9fans] Easy stating of newer files on Plan9

[tlaronde]

Hello,

I have finished to add MetaPost to kerTeX and I'm testing and polishing.

My aim is to have something strictly C89.

There is one utility used by MetaPost scripts: a binary "newer" using
POSIX (sys/stat.h) mainly because if on POSIX compliant systems one can
use find(1) with "-cnewer", Plan9 has not find(1).

3 options:

1) Let this POSIX exception "newer";

2) Drop this optimization (AFAIK) in the scripts;

3) Patch the scripts with "find..." for not Plan9, and
some ls, cut, whatever line for Plan9 just for consistency.

My preference is 3).

What would be the prefered way using utilities available on Plan9 (and
accessible for ape/sh) since the scripts are Bourne shell ones.

TIA

The Plan 9 test(1) has "newer than" and "older than"
expressions just like the Korn shell's built-in.
