When building WebKit (release, for x86-64/Linux/GTK, but actually there is/should be nothing platform or port-specific in the issue), bison is emitting the following warnings:

[190/4820] Generating ../../DerivedSources/WebCore/CSSGrammar.h, ../../DerivedSources/WebCore/CSSGrammar.cpp
/home/akiss/devel/WebKit/WebKitBuild/Release/DerivedSources/WebCore/CSSGrammar.y:576.17-25: warning: type clash on default action: <boolean> != <> [-Wother]
 supports_error: error ';' | error invalid_block ;
                 ^^^^^^^^^
/home/akiss/devel/WebKit/WebKitBuild/Release/DerivedSources/WebCore/CSSGrammar.y:576.29-47: warning: type clash on default action: <boolean> != <> [-Wother]
 supports_error: error ';' | error invalid_block ;
                             ^^^^^^^^^^^^^^^^^^^

Actually, this causes no issues when running the generated code but it would be cleaner to get rid of the warnings and make bison happy, IMHO.
