[Bug c/41215] New: request: option to suppress discarded qualifiers warnings

[adam at yorba dot org]

There is currently no GCC option that will turn off discarded qualifiers
warnings, which typically arise from const/non-const mismatches.  These
warnings look like this:

  warning: assignment discards qualifiers from pointer target type
  warning: passing argument 1 of ‘foo’ discards qualifiers from pointer target
type

This is a request for an option to suppress these warnings.

A typical C programmer should see these warnings so that they can fix them. 
But in tools that automatically generate C code it may sometimes be difficult
to avoid large numbers of warnings like this, and so as a practical matter it
may be helpful to be able to suppress them.  (One such tool is the Vala
compiler; see http://live.gnome.org/Vala).
