Merge of r4870, r4871, r4890, r4895: minor fixes. *) Made sure to initialize the entire ngx_file_t structure. Found by Coverity. *) Correct plural form for "path" in the whole source base. *) Removed conditional compilation from waitpid() error test. There are reports that call to a signal handler for an exited process despite waitpid() already called for the process may happen on Linux as well. *) Style, parentheses instead of braces in misc/GNUMakefile.
