But that cast is also not portable, and not permitted
at all in C++ -- I introduced that rule :)

Example: i386 using small data/large code model,
data pointers are 32 bits, code is 48 bits.

There is no universal function pointer type
-- one is needed though!

The following function:

void *dlsym()

is broken and can't be repaired without a universal
function pointer type, and even then, there must be TWO
distinct functions:=20

void *dldata()=20
funptr_t dlfun()


--=20
