Fixed warnings on redefine keywords and reserved ids. Repared support for warnings -Wkeyword-macro and -Wreserved-id-macro. The warning -Wkeyword-macro now is not issued in patterns that are used in configuration scripts: #define inline also for 'const', 'extern' and 'static'. If macro repalcement is identical to macro name, the warning also is not issued: #define volatile volatile And finally if macro replacement is also a keyword identical to the replaced one but decorated with leading/trailing underscores: #define inline __inline #define inline __inline__ #define inline _inline // in MSVC compatibility mode Warning -Wreserved-id-macro is off by default, it could help catching things like: #undef __cplusplus llvm-svn: 224512
