Bug ID: 61480
Summary: GCC options processing: Init() requires Var() for
'no-' to work as expected
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: gary at intrepid dot com
CC: jsm28 at gcc dot gnu.org, nenad at intrepid dot com
While researching an issue related to Bug 60439, I noticed that the
specification for the -Wswitch-bool option quietly ignored -Wno-switch-bool.
This was fixed by adding a Var() clause.

The internal document describing the format of the c.opt file didn't appear to
mention this requirement. If there is such a requirement for things to work as
expected, perhaps the tool that processes the options specification file should
issue an error when Init() is present, but Var() is not?
