http://sourceforge.net/p/predef/wiki/Compilers/

    Notice that the meaning of the __GNUC__ macro has changed subtly over the
    years, from identifying the GNU C/C++ compiler to identifying any compiler
    that implements the GNU compiler extensions (...). For example, the Intel
    C++ on Linux also defines these macros from version 8.1 (...).
