Get C compiler working

[eschaton]

Right now, trying to compile a trivial C program fails.

The trivial program, in the MINIX /usr/tmp directory as sigtest.c (which I compiled in an Atari ST emulator just fine):

#include <stdio.h>
#include <signal.h>


int did_quit = 0;

void quit_handler(sig)
    int sig;
{
    did_quit = 1;
}

int main(argc, argv)
    int argc;
    char **argv;
{
    void (*old_handler)() = signal(SIGQUIT, quit_handler);

    while (!did_quit) {
        /* do nothing */
    }

    printf("got SIGQUIT");
    return 0;
}

The command line:

$ MINIXCOMPAT_DIR=/opt/minix \
  MINIXCOMPAT_PWD=/usr/tmp \
  MINIX_HOME=/usr/ast \
  MINIX_TERM=vt100 \
  MINIX_PATH=/usr/bin:/bin \
  /usr/bin/cc -v sigtest.c -o sigtest

I'll update this in a bit with the expected and actual output.
