           Summary: Make 'go to definition' play nicer with extern(C)
           Product: D
           Version: D2
          Hardware: All
                OS: Windows
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: VisualD
          Assignee: nobody at puremagic.com

In C/C++, there are 2 features, 'go to declaration' (ctrl-alt-F12) and 'go to
definition' (F12), one generally takes you to the header file, the other takes
you to the code.
In VisualD, there only seems to be 'go to definition' (F12), this makes sense
for D code, since there are no headers, but it's not so helpful with extern(C)
functions.

It is very common to have VisualD projects alongside C/C++ projects.
Would it be possible to detect extern(C) functions, and make 'go to definition'
go to the function definition in the C code instead of the D prototype?

For completeness, it would be nice to offer 'go to declaration' (ctrl-alt-F12)
also in these cases, which would go to the prototype in the D code, just like
jumping to the header in C.
