            Bug ID: 84749
           Summary: -w does not work with option property Warn
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: segher at gcc dot gnu.org
  Target Milestone: ---

As example,

echo|i386-linux-gcc -mintel-syntax -w -xc -S -

prints

i386-linux-gcc: warning: '-mintel-syntax' and '-mno-intel-syntax' are
deprecated; use '-masm=intel' and '-masm=att' instead

while -w should shut up all warnings (there is no other way to turn off
messages
by Warn option properties either).
