Future even today:
http://sysoev.ru/tmp/patch.0.7.52.prefix

There are many changes related to the "-p prefix" switch support
and the start up error logging and I want to test them before release.

*) Change: now a log set by --error-log-path is created from the very
start up.

*) Feature: now the start up errors and warnings are outputted to an
error_log and stderr.

*) Feature: the --prefix=. configure parameter forces nginx to use
current directory as prefix.

*) Feature: the -p switch.

*) Feature: the -s switch on Unix platforms.

*) Feature: the -? and -h switches.

*) Feature: now switches may be set in condensed form.

*) Bugfix: the "fastcgi_cache_min_uses" directive did not work.
