//
// Overall warning settings: the 'all' and 'extra' classes plus convert warnings into errors.
// -Wall,  // Standard known-to-be-bugs warnings.
// -Wextra,  // Many useful extra warnings.
// -Werror,  // All warnings as errors.
//
// Deprecation support: without these one can't rationally deprecate things.
// -Wno-error=deprecated,  // Deprecation warnings are never errors.
// -Wno-error=deprecated-implementations,  // Deprecation warnings are never errors.
//
// Useful warnings that are not in the 'all' and 'extra' classes.
// -Wcast-align,  // Casting a pointer such that alignment is broken.
// -Wconversion,  // Numeric conversion warnings.
// -Wdocumentation,  // Warn when documentation is out of date.
// -Wformat=2,  // Check printf-style format strings more strictly.
// -Wimplicit-atomic-properties,  // Dynamic properties should be non-atomic.
// -Wmissing-declarations,  // Warn if a global function is defined without a previous declaration.
// -Wmissing-prototypes,  // Global function is defined without a previous prototype.
// -Wno-unused-parameter,  // Do not warn on unused parameters.
// -Woverlength-strings,  // Strings longer than the C maximum.
// -Wshadow,  // Local variable shadows another variable, parameter, etc.
// -Wstrict-selector-match,  // Compiler can't figure out the right selector.
// -Wundeclared-selector,  // Compiler doesn't see a selector.
// -Wunreachable-code,  // Code will never be reached.
