ok, I'v enabled the code that turns it into an 'INT' for now. I may add
a new type later if it is needed.

borrowing an idea from another (C++) parser I work with, I simply
ignore '__restrict' tokens.

Now 89.66% of the accept0 tests pass (yay !). The rest seems to stem
from a parse error in /usr/include/stdio.h, specifically at a line like:

extern char *tempnam (__const char *__dir, __const char *__pfx)
      __attribute__ ((__malloc__));

While the scanner supports '__attribute__', the grammar doesn't look
as if it allows it at that particular place. As I don't quite 
undererstand the grammar (yet), I don't know what change to make
to gram.y to add an optional attribute to a function declaration
like the above.
It might be a one-line fix...
