 <p><a name="index-i386-and-x86_002d64-Windows-Options-1511"></a>
 These additional options are available for Microsoft Windows targets:

      <dl>
 <dt><code>-mconsole</code><dd><a name="index-mconsole-1512"></a>This option
 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 option is available for Cygwin and MinGW targets and is
 enabled by default on those targets.

      <br><dt><code>-mdll</code><dd><a name="index-mdll-1513"></a>This option is available for Cygwin and MinGW targets.  It
 specifies that a DLL&mdash;a dynamic link library&mdash;is to be
 generated, enabling the selection of the required runtime
 startup object and entry point.

      <br><dt><code>-mnop-fun-dllimport</code><dd><a name="index-mnop_002dfun_002ddllimport-1514"></a>This option is available for Cygwin and MinGW targets.  It
 specifies that the <code>dllimport</code> attribute should be ignored.

      <br><dt><code>-mthread</code><dd><a name="index-mthread-1515"></a>This option is available for MinGW targets. It specifies
 that MinGW-specific thread support is to be used.

      <br><dt><code>-municode</code><dd><a name="index-municode-1516"></a>This option is available for MinGW-w64 targets.  It causes
 the <code>UNICODE</code> preprocessor macro to be predefined, and
 chooses Unicode-capable runtime startup code.

      <br><dt><code>-mwin32</code><dd><a name="index-mwin32-1517"></a>This option is available for Cygwin and MinGW targets.  It
 specifies that the typical Microsoft Windows predefined macros are to
 be set in the pre-processor, but does not influence the choice
 of runtime library/startup code.

      <br><dt><code>-mwindows</code><dd><a name="index-mwindows-1518"></a>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.

      <br><dt><code>-fno-set-stack-executable</code><dd><a name="index-fno_002dset_002dstack_002dexecutable-1519"></a>This option is available for MinGW targets. It specifies that
 the executable flag for the stack used by nested functions isn't
 set. This is necessary for binaries running in kernel mode of
 Microsoft Windows, as there the User32 API, which is used to set executable
 privileges, isn't available.

      <br><dt><code>-fwritable-relocated-rdata</code><dd><a name="index-fno_002dwritable_002drelocated_002drdata-1520"></a>This option is available for MinGW and Cygwin targets.  It specifies
 that relocated-data in read-only section is put into .data
 section.  This is a necessary for older runtimes not supporting
 modification of .rdata sections for pseudo-relocation.

      <br><dt><code>-mpe-aligned-commons</code><dd><a name="index-mpe_002daligned_002dcommons-1521"></a>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 is enabled by default if
 GCC detects that the target assembler found during configuration
 supports the feature.
