Location of Internal Code

Hello, This seems like a fairly elementary question, but I couldn't seem to find the answer anywhere online. Where can I find code which is called with .Internal? Specifically, the R function colSums() calls an internal function with the same name (I presume a C function), and I'd like to see how it works. I've searched through the header files in R-2.x.x/include/ (Windows version), but to no avail.
They are only used for external function to be able to link against R. For .Internal() (for example), see ./src/main/names.c and the names they refer to (also in other files in ./src/main) Uwe Ligges
Thanks, Robin
