Bug #: 11790
Summary: Don't set __GNUC__ and friends in microsoft mode, set
_MSC_VER instead
Product: clang
Version: unspecified
Platform: PC
OS/Version: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Probably important for many projects.
Chromium for example uses this for compiler detection:
// Compiler detection.
#if defined(__GNUC__)
#define COMPILER_GCC 1
#elif defined(_MSC_VER)
#define COMPILER_MSVC 1
#else
#error Please add support for your compiler in build/build_config.h
#endif
...and uses that to decide whether to #include <hash_set> or <ext/hash_set.
