В файле ext/posix/posix.c тот заголовочный файл, который (в конечном
итоге) включает php_config.h (который определяет _GNU_SOURCE), включается
слишком поздно: к этому времени features.h уже обработан.

Можно в этом ext/posix/posix.c заменить проверку _GNU_SOURCE на
проверку __USE_GNU, но, возможно, из-за неправильного включения
заголовочных файлов могут случиться и другие неприятности.
