2.17 Control Warnings: '-W', '--warn', '--no-warn', '--fatal-warnings'
======================================================================
'as' should never give a warning or error message when assembling
compiler output. But programs written by people often cause 'as' to
give a warning that a particular assumption was made. All such warnings
are directed to the standard error file.
If you use the '-W' and '--no-warn' options, no warnings are issued.
This only affects the warning messages: it does not change any
particular of how 'as' assembles your file. Errors, which stop the
assembly, are still reported.
If you use the '--fatal-warnings' option, 'as' considers files that
generate warnings to be in error.
You can switch these options off again by specifying '--warn', which
causes warnings to be output as usual.
