No it doesn't support it. (it's not really simple to compare file with
shell tools portably or set the modification time).

Strange. Before GNU fileutils 4.x I used my own hacked version of the
FreeBSD version of install, which supported -p (even fancier than GNU, it
actually _compares_ the files). So at least one BSD install supported it
;)

Hmm. I must have missed (or forgot ;) ) that mail. What was it about?

Anyway, I just commited an ugly M4 macro (one could say it's an autoconf
macro, but as it is so ugly...) to override the autoconf default for
searching a suitable configure. Its actually further uglified by the fact,
that I tried to reuse the old macro, without including its GPL'ed code
into our LGPL'ed acinclude.m4.in. If you haven't set the $INSTALL, it
tests install for a -p flag. If that worked, it uses it. So beware, if -p
for your install means "eat flaming death" you loose. But as I see it,
either -p gets ignored, does something reasonable or it's not supported on
the installs I read the manpages from. So try it.


Ciao,
Michael.
