Clang complains about function without prototype

[webisu]

The clang compiler is now giving warnings

warning: passing arguments to a function without a prototype is deprecated in all versions of C and is not supported in C2x [-Wdeprecated-non-prototype]

Yes, well the warning says it all, doesn't it.

Write prototypes for your functions in a .h file. I usually have a public .h file, and at least one internal .h file. For example on netcdf-c, we have public-facing netcdf.h, and internal-only nc3internal.h, nc4internal.h.

Can you add one or more internal .h files with the missing prototypes?

Wgrib2 uses pointers to functions, and the arguments to the pointer-functions were never prototype-ed. The new clang is the first compiler to rightly warn about the omission.
