When introducing new compiler flags, you need to do one of:

1. Verify that the flags are supported on all versions of the compiler we support. There is a minimum version defined for each. Reading the documentation to find out when the compiler feature was introduced is enough, you don't need to actually test every version yourself.
2. If 1 couldn't be proved, then only add the flag conditionally with a check in configure.
