Does not compile with gcc 4.6.2

[vadim-skorba]

Hi, Valery

I've tried to compile other nginx versions (1.0.11 - 1.1.15) on server with gcc 4.6.2 with last (https://github.com/vkholodkov/nginx-eval-module/commit/125fa2e97399d29ce148f55cc6975268e482d212) version of that module and it was failed with such errors:

../nginx-eval-module/ngx_http_eval_module.c: In function ‘ngx_http_eval_block’: ../nginx-eval-module/ngx_http_eval_module.c:640:39: error: variable ‘pclcf’ set but not used [-Werror=unused-but-set-variable] ../nginx-eval-module/ngx_http_eval_module.c:631:32: error: variable ‘ecf’ set but not used [-Werror=unused-but-set-variable] The problem is - new gcc becomes smarter and for now unused variables throws warnings. Nginx default config is: -Werror=unused-but-set-variable] So, it would be great to fix module instead of changing nginx default options.

Thank you! Vadim.
