+		Issue all the warnings demanded by strict ISO C and ISO C++; reject all programs that use forbidden extensions, and some other programs that do
+		not follow ISO C and ISO C++.  For ISO C, follows the version of the ISO C standard specified by any -std option used.
+
+		Valid ISO C and ISO C++ programs should compile properly with or without this option (though a rare few require -ansi or a -std option
+		specifying the required version of ISO C).  However, without this option, certain GNU extensions and traditional C and C++ features are
+		supported as well.  With this option, they are rejected.
+
+		-Wpedantic does not cause warning messages for use of the alternate keywords whose names begin and end with __.  This alternate format can also
+		be used to disable warnings for non-ISO __intN types, i.e. __intN__.  Pedantic warnings are also disabled in the expression that follows
+		"__extension__".  However, only system header files should use these escape routes; application programs should avoid them.
+
+		Some users try to use -Wpedantic to check programs for strict ISO C conformance.  They soon find that it does not do quite what they want: it
+		finds some non-ISO practices, but not all---only those for which ISO C requires a diagnostic, and some others for which diagnostics have been
+		added.
+
+		A feature to report any failure to conform to ISO C might be useful in some instances, but would require considerable additional work and would
+		be quite different from -Wpedantic.  We don't have plans to support such a feature in the near future.
+
+		Where the standard specified with -std represents a GNU extended dialect of C, such as gnu90 or gnu99, there is a corresponding base standard,
+		the version of ISO C on which the GNU extended dialect is based.  Warnings from -Wpedantic are given where they are required by the base
+		standard.  (It does not make sense for such warnings to be given only for features not in the specified GNU C dialect, since by definition the
+		GNU dialects of C include all features the compiler supports with the given option, and there would be nothing to warn about.)

+			time.
+	config BUILD_O2
+		bool "-O2"

+			It also enables -finline-functions, causes the compiler to tune for code size rather than execution speed, and performs further optimizations
+			designed to reduce code size.
+	config BUILD_Ofast

+		help
+			Optimize debugging experience.  -Og should be the optimization level of choice for the standard edit-compile-debug cycle, offering a reasonable
+			level of optimization while maintaining fast compilation and a good debugging experience.  It is a better choice than -O0 for producing
+			debuggable code because some compiler passes that collect debug information are disabled at -O0.
+			Like -O0, -Og completely disables a number of optimization passes so that individual options controlling them have no effect.  Otherwise -Og
+			enables all -O1 optimization flags except for those that may interfere with debugging:
