Yes, but this does not explain why the AT&T C++ translator chokes. It turns
out that although the translator will not swallow this declaration, the
following goes down without a whimper:

typedef double (*PFD)() ;

extern int bob(PFD) ;

Furthermore, B. Stroustrup's C++ text claims that the first declaration
should be valid (see Section 8.7).
