[Mono-list] mono on FC4 - let's get it working!

[Alex Roman]

I've made 2 test files:
1.h:
--snip--
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

typedef struct {
        char*   string;
        int     length;
} String;
--snip--

1.c:
--snip--
#include "1.h"

String s;

int main (int argc, char** argv) {
        s.string = (char*)malloc(10);

        strcpy(s.string, "hi");

        printf("%s\n", s.string);

        return 0;
}
--snip--

I've compiled them:
$ gcc 1.c -o 1

And I ran 1:
[aroman at idaho structs]$ ./1
hi

As you can see, the syntax seems to work in this case... Why not in the case of gdip.h I wonder?
