dnl
dnl This macro is scanned by genif.sh when it builds the internal functions
dnl list, so that modules can be init'd in the correct order
dnl $1 = name of extension, $2 = extension upon which it depends
dnl $3 = optional: if true, it's ok for $2 to have not been configured default
dnl is false and should halt the build. To be effective, this macro must be
dnl invoked *after* PHP_NEW_EXTENSION. The extension on which it depends must
dnl also have been configured. Due to the limited genif.sh parsing and regex
dnl matching implementation, this macro must be called on its own line, and its
dnl arguments must be passed unquoted (without Autoconf '[' and ']' characters.
dnl For Windows, see 'ADD_EXTENSION_DEP' in the win32 build.
