[RFC] Accomodate 64-bit msymbols in expressions

[Michael Snyder]

The following change is motivated by the fact that the addresses of
minimal symbols currently get truncated to 32 bits in expressions.

Does this look badly wrong to anybody?

	* parse.c (write_exp_msymbol): Make the type (long long), to 
	accomodate 64-bit addresses.
