>Description:
A legal definition like

  (char(*)(int)) (* x) (long const*, wchar_t);

(i.e. x is a pointer to a function accepting a (long const*)
and a wchar_t, and returning in turn a pointer to a function 
accepting an int and returning a char) is rejected with 
the error message

  parse error before `char'

>How-To-Repeat:
Just compile this file (with gcc -c).
>Fix:
Provide a typedef for the resulting type, i.e.

typedef char(*F)(int);
F (* x) (long const*, wchar_t);
