In the warning table entry, the compiler switch /GR- should be formatted as code (backticks) for consistency with the other rows and the repo guideline to use backticks for command-line switches.

The warning text blockquote shows /GR- without code formatting. Use backticks around /GR- (consistent with other switch references like /GR in the Remarks section and the repo guideline for command-line options).
