0.3 compatibility

[stevengj]

Currently, it only works with 0.4, which is not really acceptable.

Got it at least loading with 0.3, but have some kind of weird corruption that I can't figure out in 0.3:

julia> using DecFP
julia> d"1.0"
+140734667966048E-398
julia> reinterpret(Uint64, d"1.0")
0x0000000000000000

Something has apparently changed with how bitstype is handled? (cc: @vtjnash)

I'm not sure it's actually worth it. I can just make this package require Julia 0.4.

[vtjnash]

it's quite possible the ccall fixes changed the calling convention for Dec128, depending on what the system you are on

[stevengj]

But why would this affect Dec64 (on 64-bit MacOS X)?

[vtjnash]

nvm, it shouldn't i just skimmed the code too quickly.

unrelated note: cglobal (like ccall) is a compile-time intrinsic, so it is zero-cost to copy it to each usage site (perhaps in macro form @flags to reduce typing?) instead of putting it in __init__

Just close, since "it only works with 0.4, which is not really acceptable" is just no longer true..
