* printcmd.c (do_examine): Make meaning of 'h', 'w', and 'g' not
depend on builtin_type_*. Instead, it is always 2, 4, and 8 bytes like the documentation says. * printcmd.c (decode_format) [CC_HAS_LONG_LONG]: Remove 'l' as synonym for 'g'. This was never documented, it shouldn't depend on CC_HAS_LONG_LONG, and I don't see what's wrong with 'g'.
