is a valid label. This warning can be suppressed with \c{-w-ptr},
the \c{[warning]} directive (see \k{opt-w}) or by the macro
definition \c{%idefine ptr %??}.
\b When an error or a warning comes from the expansion of a multi-line
macro, display the file and line numbers for the expanded macros.
Macros defined with \c{.nolist} do not get displayed.

\b \i\c{zext-reloc} warns that a relocation has been zero-extended due
to limitations in the output format.
\b \i\c\{ptr} warns about keywords used in other assemblers that might
indicate a mistake in the source code. Currently only the MASM
\c{PTR} keyword is recognized.
\b \i\c{error} causes warnings to be treated as errors. Disabled by
default.
\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.
In addition, you can control warnings in the source code itself, using
the \i\c{[warning]} directive.
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"
