A macro to detect real GCC

Reported by: Andrey Semashev Owned by: John Maddock
Milestone: To Be Determined Component: config
Version: Boost 1.52.0 Severity: Problem
Keywords: Cc:

Description

Please provide a macro to detect the real GCC. Different compilers try to emulate GCC by defining GNUC and similar macros, which makes it difficult to work around GCC-specific bugs. The macro can expand to the GCC version number, like BOOST_MSVC: 

#define BOOST_GCC (__GNUC__ * 10000 + __GNUC_MINOR__ * 100 + __GNUC_PATCHLEVEL__)

This macro only has to be defined in compiler/gcc.hpp.
