I'm still unclear whether we're aiming for C interoperability or hardware
support though, based on Walter's remark about SPARC and PPC. There, 'long
double' is represented differently but is not backed by specialized hardware, so
I'm guessing D would make 'real' 64-bits on these platforms and break
compatibility with C. So... I guess we really do need a special alias for C
compatibility, and this can map to whatever intrinsic type the applicable
compiler supports for that platform.
What is unclear about being able to call a C function declared as:
int foo(long double r);
from D?
