--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
The optimization can be disabled for format strings containing floating point
directives by using -frounding-math.  The locale-specific radix character is a
POSIX extension to C that I missed.  I agree that it means that the
optimization cannot be enabled when there are floating point directives in the
format string that may include it.
