Re: Error: attempt to get value of unresolved symbol `L0'
* symbols.c (S_GET_VALUE): If the unresolved symbol is the fake
label provide a more helpful error message to the user.
(S_GET_VALUE_WHERE): Like S_GET_VALUE, but includes a file/line
number for error reporting purposes.
* symbols.h (S_GET_VALUE_WHERE): Prototype.
* write.c (fixup_segment): Use S_GET_VALUE_WHERE.
