# Qgcc-dialect

Enables support for a limited gcc-compatible dialect on Windows*.

## Syntax

Linux and macOS: | None

Windows: | /Qgcc-dialect:ver

## Arguments

ver | Indicates the version of the gcc compiler that the limited language dialect should be compatible with. It must be a three-digit number with a value of 440 or higher. The number will be normalized to reflect the gcc compiler version numbering scheme. For example, if you specify 450, it indicates gcc version 4.5.0.

## Default

OFF | The compiler does not support a language dialect that is compatible with the gcc compiler.

## Description

This option enables support for a limited gcc-compatible dialect on Windows*. It allows portability of code written for the gcc compiler.

This option enables a limited gnu-compatible compiler dialect on Windows. The code will be compiled with syntax and semantics similar to that used by gcc, while continuing to produce object files that are link-compatible with the object files and libraries on Windows (that is, object files and libraries produced by the Microsoft compiler and/or by the Intel compiler without this option).

The /Qgcc-dialect option is intended to be used as an aid in porting code written for the gcc compiler. It is not intended to enable an all-encompassing capability for porting all such code written for the gcc compiler seamlessly. For example, even with this option enabled, there remains a need to support Windows-compatible syntax and semantics for some language constructs in order to generate object files that are link-time compatible with those produced by the Windows compiler and/or by the Intel compiler without this option.
