        <title>Space required</title>
	<para>
	  You also need about 230 MB of available disk space for compilation.
	  The compiled libwine.so binary takes around 5 MB of disk space,
	  which can be reduced to about 1 MB by stripping ('strip wine').
	  Stripping is not recommended, however, as you can't submit
	  proper crash reports with a stripped binary any more.

        <title>Common problems</title>
	<para>
	  If you get a repeatable sig11 compiling shellord.c, thunk.c
	  or other files, try compiling just that file without optimization.
	  Then you should be able to finish the build.
