The ANSI/ISO standard for the C language requires that certain predefined macros be supplied with conforming compilers. The following table lists the macros that the Intel® C++ Compiler supplies in accordance with this standard:
The compiler includes predefined macros in addition to those required by the standard. The default predefined macros differ among Windows*, Linux*, and Mac OS* X operating systems due to the default /Za compiler option on Windows. Differences also exist on Linux OS and Mac OS X as a result of the -std compiler option.
