nginx-0.3.41-RELEASE importrelease-0.3.41

    *) Feature: the -v switch.

    *) Bugfix: the segmentation fault may occurred if the SSI page has
       remote subrequests.

    *) Bugfix: in FastCGI handling.

    *) Bugfix: if the perl modules path was not set using
       --with-perl_modules_path=PATH or the "perl_modules", then the
       segmentation fault was occurred.
