dnl config.m4 for extension mycoroutine

dnl Comments in this file start with the string 'dnl'.
dnl Remove where necessary. This file will not work
dnl without editing.

dnl If your extension references something external, use with:

PHP_ARG_WITH(mycoroutine, for mycoroutine support,
Make sure that the comment is aligned:
[  --with-mycoroutine             Include mycoroutine support])

dnl Otherwise use enable:

dnl PHP_ARG_ENABLE(mycoroutine, whether to enable mycoroutine support,
dnl Make sure that the comment is aligned:
dnl [  --enable-mycoroutine           Enable mycoroutine support])
