I'm relatively inexperienced piling C code. Nevertheless, I'm trying to use emscripten to pile an algorithm from the R source code into JavaScript. The function is in a file called pf.c here

Naively, I have just gone into the src directory and tried:

emcc nmath/pf.c 

This results in:

In file included from nmath/pf.c:25:
nmath/nmath.h:38:10: fatal error: 'Rconfig.h' file not found
#include <Rconfig.h>
         ^
1 error generated.
ERROR    root: piler frontend failed to generate LLVM bitcode, halting

I know where this header is:

$ find . -name "Rconfig.h"
./gnuwin32/fixed/h/Rconfig.h

My immediate question is, how do I tell the piler where this header exists? I'd like to end up with a pf function in JavaScript. Any insight into this idea would be appreciated.

Use -I to add to the include search path.

emcc nmath/pf.c -Ignuwin32/fixed/h/

Regarding the overall idea... sounds weird, I don't know.
