Ethereal 0.10.10 on RELENG_4

[Troy]

I just tried to build Ethereal on RELENG_4 and ran into this error. It
seems to build fine on RELENG_5.

o.TPlo  -fPIC -DPIC -o .libs/packet-spnego.o
packet-spnego.c: In function `arcfour_mic_key':
packet-spnego.c:426: `KEYTYPE_ARCFOUR_56' undeclared (first use in this
function)
packet-spnego.c:426: (Each undeclared identifier is reported only once
packet-spnego.c:426: for each function it appears in.)
