Here's a simple org file that's supposed to run some C code and print the r=
esult:

----------------------

* Sample C code

#+name: RHS.c
#+begin_src C :noweb yes :tangle RHS.c
  #include <stdio.h>
  <<main>>
#+end_src

#+name: main
#+begin_src C
  int main(int argc, char *argv[]) {
    int lst[argc-1];
    int i;
    for(i=3D1;i<argc;i++)
      lst[i-1] =3D atoi(argv[i]);
    for(i=3D1;i<argc;i++)
      printf("%d ", lst[i-1] + 1);
    printf("\n");
}
#+end_src

#+call: RHS.c[:cmdline 8 7 6]()

-------------------------

It works fine on my Mac, producing the result:

#+RESULTS: RHS.c[:cmdline 8 7 6]()
: 9 8 7

On my PC, however, running Windows Vista, the output is blank and there's a=
 *Org-babel-error-output* buffer containing the message

Access is denied.
'c:/Users/stanton/AppData/Local/Temp/babel-11948MQP/C-bin-11948Nln' is not =
recognized as an internal or external command,
operable program or batch file.

There is a file called C-bin-11948Nln in that directory, but it has length =
0, suggesting that something is going wrong in the compilation process. How=
ever, I can also see potential problems with the fact that the file name do=
es not end in .exe, so the Windows shell is not easily going to recognize i=
t as an executable anyway.

Does anyone have this running OK under Windows? Alternatively, how can I tr=
ack down what's going wrong in more detail?

Thanks.
