Stephen Kelly	b15c008fac	Features: Record for GNU 4.6. Adjust the CompileFeatures genex_test for the expectation of the OVERRIDE_CONTROL feature group.	2015-01-16 00:11:01 +01:00
Stephen Kelly	222ec86f7d	Features: Test an old value of __STDC_VERSION__ for GNU < 4.7 compatibility.	2015-01-15 22:13:22 +01:00
Stephen Kelly	d0af0faefb	WCDH: Make the header -Wundef safe for the C language. The __STDC_VERSION__ macro may be defined or not depending on the implementation dialect of C. Test that it is defined before testing its value. The CXX tests do not need such a change because they define __cplusplus in all dialects.	2014-11-25 14:44:21 +01:00
Stephen Kelly	e0890d03a4	Features: Extend concept to C language. Add properties and variables corresponding to CXX equivalents. Add features for c_function_prototypes (C90), c_restrict (C99), c_variadic_macros (C99) and c_static_assert (C11). This feature set can be extended later. Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader to conditionally represent the c_restrict feature.	2014-05-15 00:15:18 +02:00
