>Description:
The port www/netsurf is currently marked as BROKEN as it does not build.

The reason is, that the file generated by the parser generator uses assert(3)
but does not #include <assert.h>; as assert(3) is a macro, this is bound to
fail at linking stage.
>How-To-Repeat:
	Try to build the port, even after removing the BROKEN line from the Makefile.
>Fix:

Add the attached file patch-css-parser.y into the files directory of
the port. Then remove the BROKEN line in the Makefile.

PS:
I'm aware that this is only a temporary solution, as the port ought to
be updated to the newest version; however, this is a bit more work and
therefore will take longer than just making the current version build again.
