Thus one has conversions of a pointer (char *) to unsigned long. This is implementation-defined and can even be undefined behavior if "the result cannot be represented in the integer type", in particular if unsigned long is smaller than pointers (e.g. with the LLP64 data model, like under MS Windows64).
Thanks, Vincent. It always seemed a bit dubious to me, but since it has been that way for 25 years, I figured "let it be". :-)
IMHO, the best solution for safety would be to use a union (I think that this would require the use of C99 designators for the MuttVars initialization).
Okay, I will work on this. I think it's better to fix this the right way now then get bitten by this later.
