ringtools/imy: fix duplicate definition of tdma_durations[] The bug was reported by Vadim Yanitskiy <fixeria@osmocom.org>, although the present fix is slightly different from the contributed patch: because main.c doesn't need this tdma_durations[] array at all, let's simply remove the reference to this array from main.c rather than turn it into an extern. I no longer remember my original thought flow that resulted (by mistake) in tdma_durations[] being multiply defined in main.c and durations.c. My intent might have been to define all globals in main.c and have the reference in durations.c be an extern - and I missed that extern - but without clear memory, I have no certainty. In any case, having this data array defined in the same module that fills it (durations.c) is sensible, so let's make it the new way.

/*
 * host_mkdir() function has been factored out into this module.

#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include "exitcodes.h"

host_mkdir(pathname)
	char *pathname;
{
	int rc;
	struct stat st;

	rc = stat(pathname, &st);
	if (rc < 0) {
		rc = mkdir(pathname, 0777);
		if (rc < 0) {
			perror(pathname);
			return(ERROR_UNIX);
		}
		return(0);
	} else {
		if (S_ISDIR(st.st_mode))
			return(0);
		else {
			fprintf(stderr,
			"error: %s already exists and is not a directory\n",
				pathname);
			return(ERROR_UNIX);
		}
	}
}
