As a result, the existence of fork() is not tested and HAVE_FORK is not defined. ext/standard/proc_open.c has a chain of preprocessor if blocks that expects one of PHP_WIN32, NETWARE or HAVE_FORK to be set whenever PHP_CAN_SUPPORT_PROC_OPEN is set. Reproduce code: --------------- Remove config.cache then run configure twice without --enable-pcntl (which also tests for fork()). Diff the two generated php_config.h files. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50315&edit=1
