Fixed classic sign extension bug `-(long)sizeof(foo)'.

Browse Source 
Fixed the type of the string table size variable to match its use
(assuming that int32_t is 4 bytes and other unportable things).
bfd uses `unsigned char string_chars[BYTES_IN_WORD]', where
BYTES_IN_WORD can be 4, 8, or perhaps even 2 or 3, but it is
assumed to be precisely 4 bytes here.

Fixed printf format errors (don't assume that n_value in struct
n_list has type u_long, since it should have size BYTES_IN_WORD
and longs may be longer than words).
