\b \i\c{all} is an alias for \e{all} suppressible warning classes (not
including \c{error}). Thus, \c{-w+all} enables all available warnings.
In addition, you can set warning classes across sections.
Warning classes may be enabled with \i\c{[warning +warning-name]},
disabled with \i\c{[warning -warning-name]} or reset to their
original value with \i\c{[warning *warning-name]}. No "user form"
(without the brackets) exists.
Since version 2.00, NASM has also supported the gcc-like syntax
\c{-Wwarning} and \c{-Wno-warning} instead of \c{-w+warning} and
\c{-w-warning}, respectively.
