Re: RFA: Sanitize deprecation messages (PR 84195)

Hi Martin, Hi David,

OK - attached is a new patch that:

  * Replaces control characters with their escape equivalents.
  * Includes a testcase.

I was not sure what to do about the inconsistencies between the
behaviour of #warning and #pragma GCC warning, (and the error
equivalents), so I decided to leave it for now.  Fixing them
will require mucking about in the C preprocessor library, which
I did not fancy doing at the moment.

So, is this enhanced patch OK now ?

Cheers
  Nick
