>Subject: [PATCH xkbcomp] When a file contains several maps, look for a default map
>
>Rather than always taking the first one in the file. This is exactly the
>intended use of the 'default' flag.
>
>Note that pretty much the same code is duplicated in xkbcomp.c when
>compiling a single file from the command line, but there it is
>implemented correctly (look for XkbLC_Default).
