#### 3.17.16 i386 and x86-64 Windows Options

These additional options are available for Windows targets:

`-mconsole`
  This option is available for Cygwin and MinGW targets. It specifies that a console application is to be generated, by instructing the linker to set the PE header subsystem type required for console applications. This is the default behavior for Cygwin and MinGW targets.
`-mdll`
  This option is available for Cygwin and MinGW targets. It specifies that a DLL - a dynamic link library - is to be generated, enabling the selection of the required runtime startup object and entry point.
`-mnop-fun-dllimport`
  This option is available for Cygwin and MinGW targets. It specifies that the dllimport attribute should be ignored.
`-mthread`
  This option is available for MinGW targets. It specifies that MinGW-specific thread support is to be used.
`-municode`
  This option is available for mingw-w64 targets. It specifies that the UNICODE macro is getting pre-defined and that the unicode capable runtime startup code is chosen.
`-mwin32`
  This option is available for Cygwin and MinGW targets. It specifies that the typical Windows pre-defined macros are to be set in the pre-processor, but does not influence the choice of runtime library/startup code.
`-mwindows`
  This option is available for Cygwin and MinGW targets. It specifies that a GUI application is to be generated by instructing the linker to set the PE header subsystem type appropriately.
`-fno-set-stack-executable`
  This option is available for MinGW targets. It specifies that the executable flag for stack used by nested functions isn't set. This is necessary for binaries running in kernel mode of Windows, as there the user32 API, which is used to set executable privileges, isn't available.
`-mpe-aligned-commons`
  This option is available for Cygwin and MinGW targets. It specifies that the GNU extension to the PE file format that permits the correct alignment of COMMON variables should be used when generating code. It will be enabled by default if GCC detects that the target assembler found during configuration supports the feature.
