>Description:
gcc is confused by overloaded functions used as default
arguments in function definitions. The error suggests that
the ability to distinguish which version of the overloaded
function has been deliberately not implemented, but I
thought I'd bring it to your attention just in case.
>How-To-Repeat:
Compile the included file.
>Fix:
Leave out the defeault argument, or explicitly give the type information for the function argument. 
i.e.: replace the definition of the function with:
void b(void f(double)=(void (*)(double))a){ }
