6.2.5 para 26

It does not specify the exact bit arrangements, but it does require that
void* has the same representation a pointer to a character type.

I'll concede that it does not specify which of three character types is
refered, nor can I justify that the standard requires the three types of
pointer-to-character (char*, unsigned char* and signed char*) are required
to have the same representation.

In this day and age though, you shouldn't need to assume that void* and
char* have the same internal representation.

Bill, bad comma-dian.
