Yes.
It's no harder to extract the same information from
int foo(a, b)
char *a;
double b;
{
than from
int foo(char *, double b)
{
which is what I think your point boils down to.
The type info is there. Prototypes are juts a crutch for type checking,
which allows C to retain the model of translation taking place without
any global knowledge about the program, other than what is brought in
via #include. They are a quick and dirty way to almost achieve support
for modularity in the language with the assistance of a textual preprocessor,
nothing more.
Code cross referencing and browsing tools cannot reasonably follow the same
limitation of dealing with one translation unit.
Do prototypes make it easier to make such tools? I don't see how. If you write
a great tool that cross-references material from K&R C code bases, it is extra
work to adapt that tool to handle prototypes, even just to recognize and ignore
them.
