Yes.

I think back ends should be able to register non-deferred pragmas, which 
should be allowed everywhere (and wouldn't reach the parser at all), like 
the ident pragma of the motivating case for this PR, but it's for the 
person adding such a pragma to add the facilities required.  #pragma weak 
is one I think it is entirely appropriate to allow only at limited places 
in the grammar rather than trying to define what it means in the middle 
of a declaration.

But I'm not convinced we want to allow pragmas in this context.  While these
pragmas aren't covered by the C standard, for all the covered pragmas in there
they must appear outside of external declarations or explicit declarations and
statements inside a compound statement.  While there was a point in handling
some pragmas inside of structure/union definition, pragmas at this spot don't
serve anything useful and allowing it here would mean
basically we'd need to handle pragmas almost everywhere in the grammar.

Confirmed, this is most likely caused by the pragma changes in 4.2 as 4.1.1
works.
