For some reason the parser was not rebuilt. The tar file contains a new
version of c-parse.y which should have replaced the old version. You 
need to have Bison built and installed. Make sure that you got the c-parse.y
file from the tar file, then delete 'c-parse.tab.*' in the gcc directory and
rebuild.

Otherwise, you could produce versions of the header files with the
syntax extensions removed since they are only ignored by the modified
gcc parser anyway. But it would be easier to just rebuild the parser.
