some types probs using 3.3.1

[Ozzy]

allright,

i've successfully installed the 3.3.1
and some slightly things are different:
 -fallow-single-precision has dissapeared (why not)
i want to use 64Bits data types (integers) and 128bits for intrinsics,
is this correct to use: long long for 64bits integers and mm128 for
intrinsics? Moreover i've got an 'integer constant is too large' when i
need to initialise one of my 64bits integer variable like:  myvar =
0xffffffffffffffff; how to get rid of it?

thx.

Ozzy.
