All the 16 bit values were gone yestereday... the current
tenderbox failure is not SCTP.. at least not the ones I have
seen... its :

DHAVE_KERNEL_OPTION_HEADERS -include opt_global.h -fno-common 
-finline-limit=15000 --param inline-unit-growth=100 --param 
large-function-growth=1000 -fno-builtin -mcmodel=medlow -msoft-float

*** Error code 1

and I don't think sctp is involved in this.. at least  not to my knowledge
