Controlling Standard C Conformance

The compiler offers settings that verify how closely your source code conforms to the ISO/IEC 9899-1990 C standard ("C90"). Enable these settings to check for possible errors or improve source code portability.

Some source code is too difficult or time-consuming to change so that it conforms to the ISO/IEC standard. In this case, disable some or all of these settings.

The following table shows how to control the compiler's features for ISO conformance.
