Description:
------------
After loading php_gettext.dll, the dcngettext() function is not defined. I don't know if it is related but gettext defines a '_' (underscore) function, which seems to accept only one argument, but I don't know what this function does.

I don't know if it is specific to Windows as I haven't tried it on another system.


Reproduce code:
---------------
dl('php_gettext.dll');
$ext=new ReflectionExtension('gettext');
foreach ($ext->getFunctions() as $func) echo $func->getName()."\n";


You can also try '_('foo');' which doesn't seem to do anything.

Expected result:
----------------
textdomain
gettext
dcngettext
dgettext
dcgettext
bindtextdomain
ngettext
dngettext
bind_textdomain_codeset

Actual result:
--------------
textdomain
gettext
_
dgettext
dcgettext
bindtextdomain
ngettext
dngettext
bind_textdomain_codeset
