kf in mos1 model

Hi there.

kf in the static instance of MODEL_BUILT_IN_MOS1 (initialized in
d_mos1.cc, line 39) depends on the compiler. i think this is bad.

as it seems, g++-4.7 compiled code comes up with a zeroed-out kf
(kf.has_good_value() returns true), although kf._v has been initialized
to NOT_INPUT before. llvm compiled code does retain kf._v == NOT_INPUT
(i.e. !kf.has_good_value()).

adding traces to the respective constructors, this is what i get during startup (with g++).

it is not something i had expected (p is a BASE_SUBCKT*, 30011 is a prime).

eventually, the output of
"""
gnucap> model m nmos1
gnucap> list
"""
varies (watch out for "kf=", which is only there in the g++ case, because of
kf.has_good_value()).

i tried with these (which compilers do you use?).

it doesn't look like a gnucap bug, does it?
