title: How to find out which .c file contains the .c functions of R internals, on Windows?
body: <p>I want to view the source code of R's <code>match.call</code> function. As it is an internal function, I downloaded the R source code, went to ./src/main/names.c and looked for <code>match.call</code> there. </p>
  
  <p>Thus, I found out that the corresponding .c function is called <code>do_matchcall</code>. Ok, but how can I find out which of the dozens of .c files in ./src/main/ contains the function <code>do_matchcall</code>?</p>
  
  <p>Btw I'm using a Windows machine, in case that makes a difference.</p>
