在tengine编译模块失败

春哥，用最新的这个模块编译进tengine 2.1.1时，报如下错误：
/root/source/tengine/headers-more-nginx-module/src/ngx_http_headers_more_headers_in.c
/root/source/tengine/headers-more-nginx-module/src/ngx_http_headers_more_headers_in.c:142:18: error: ‘ngx_http_process_header_line’ undeclared here (not in a function)

编译器为4.8.2，请春哥指点

Start with src/ngx_http_headers_more_headers_in.c at line 142 and the included src/ngx_http_headers_more_headers_in.h and src/ngx_http_headers_more_filter_module.h. Reproduce the build against tengine 2.1.1 with compiler 4.8.2, then trace the reported undeclared ngx_http_process_header_line and missing handler initializer; done means the module compiles successfully.
