I was planning on proposing something like:

	#pragma GCC diagnostic [warning|error|ignore] -Wprecision-mismatch

The diagnostic machinery already has support for some of this, I had
hoped to find time to make it fine-grained, allowing you to override
the KIND of each warning, and thus override -Werror on a
per-warning-type basis.

I had planned on forcing the user to place these pragmas before the
first function definition, otherwise it becomes difficult to track
when various warnings are in force.
