Is void* compatible with function pointers?

For 16 bit programs, function pointers can be different sizes from data 
pointers. But D doesn't support 16 bit programming, and I know of no 32+ bit 
platform that does this.

It is possible to put the x86 in a mode with 48 bit function pointers, but so 
far as I know no C compiler allows that anyway.

I'd say they were the same size. If, by some quirk, someone wants to port D to a 
platform where this was not true, they could certainly get it to work, but I 
don't think it is practical to burden the other 99.99999% with worrying about that.
