Can anybody help me figure out why my cl compiler (or pre-processor)
can't find the standard header files. For instance, I have a simple C
program:

#include <stdio.h>

void main() {
  printf("Hello world\n");
  return;
}

I compile it from the directory that it's in with the command: cl
test.c

And I get the following error message:

test.c(1) : fatal error C1083: Cannot open include file: 'stdio.h': No
such file or directory

Anybody know what I can do about this?

Thanks,

Jay
