+      Updates to GCC include the <package>MinGW</package> cross-compiler.  One of the most notable changes is that the default exception handling model for the <function>win64</function> target was changed from <function>SjLj</function> to <function>SEH</function>. The <function>win32</function> target still uses the <function>SjLj</function> exception handling model. This causes all binaries for the <function>win64</function> target which use exception handling to depend on <filename>libgcc_s_seh-1.dll</filename> instead of <filename>libgcc_s_sjlj-1.dll</filename>.
