Firefox 41.1 fails build on Current AMD64

[Manfred Antar]

Should be firefox 41.1 in subject not 14

When building firefox on current this happens:
In file included from /usr/ports/www/firefox/work/mozilla-release/obj-x86_64-portbld-freebsd11.0/dom/base/Unified_cpp_dom_base1.cpp:137:
In file included from /usr/ports/www/firefox/work/mozilla-release/dom/base/Navigator.cpp:42:

gmake[7]: *** [Unified_cpp_dom_base1.o] Error 1

This is on current as of Oct 6th 12:00pm PDT.
As per UPDATING DBSTAT is enabled in sqlite3
My build options for firefox:

DBUS
GIO
GSTREAMER
ALSA
GTK2

are the only things enabled.
This has always worked till now.
Thanks
