PHP FastCGI, mod_fcgi print warnings

[felic]

Hi,

while trying to solve image upload problems (https://processwire.com/talk/topic/7749-max-image-dimensions-not-a-recognized-image-bug/) i had a look at the php error.log. There are several rather similar warnings there i understand (s. http://php.net/manual/en/security.intro.php) but not sure to evaluate them in conjunction with PW.

Something like:

[Mon Sep 14 13:34:14 2015] [warn] [client 79.193.219.101] mod_fcgid: stderr:  in Unknown on line 0, referer: [xxx]
[Mon Sep 14 14:19:47 2015] [warn] [client 79.205.24.246] mod_fcgid: stderr: PHP Warning:  Adding option (Name: 'magic_quotes_gpc' Value: '0') (16, 1) failed!
[Mon Sep 14 14:19:47 2015] [warn] [client 79.205.24.246] mod_fcgid: stderr: PHP Warning:  Adding option (Name: 'magic_quotes_sybase' Value: '0') (19, 1) failed!
[Mon Sep 14 14:19:47 2015] [warn] [client 79.205.24.246] mod_fcgid: stderr: PHP Warning:  Adding option (Name: 'register_globals' Value: '0') (16, 1) failed!

Setup: PHP 5.4.45-0+deb7u130, mysql 5.5.44-0+deb7u1-log, PW 2.6.1stable

I do not experience misbehavior so far while using PW (except this image upload one), but i am curious if this could lead to any problems soon.

Thx.
