findutils 4.6.0 v. Tru64 (strftime() v. "%F"?)

[Steven M. Schweda]

   I recently built findutils 4.6.0 on a DEC/Compaq/HP[E] Tru64 system
with imperfect results:

urtx# touch fred
urtx# /usr/local/bin/find . -name fred -printf '%C+\n'
%F+13:28:57.0000000000

   My (quick, unreliable) analysis suggests that this is caused by use
of the (old/lame) Tru64 strftime(), which does not support "%F".  The
findutils "configure" script seems to think that any old strftime() is
good enough:

      checking for strftime... yes

      urtx# grep -i strftime config.h
      /* Define to 1 if you have the `strftime' function. */
      #define HAVE_STRFTIME 1
      /* Define to the name of the strftime replacement function. */
      #define my_strftime nstrftime

But this one apparently isn't.

   Interestingly, the findutils kit includes a (gl/lib/) strftime.c, but
it seems to be built with special options to provide nstrftime() (and
strftime_case_()?), but not a plain GNU strftime(), which seems to be
needed here.

   Should the findutils builders (or I) be more clever, or should I have
a whole GNU run-time library (with a better strftime()) available
independently, or is Tru64 just too old to be tolerated nowadays, or
what?
