This might not be what you want, however, I worked around this with the
following code:
/* getopt_long is not available on some systems, even if they have glibc2.2 */
#if HAVE_GETOPT_H
#include <getopt.h>
#else
#include <unistd.h>
#define getopt_long(a,b,c,d,e) getopt(a,b,c)
struct option {
const char *name;
enum { required_argument, no_argument } arg;
void *unused;
char val;
};
#endif
This worked for me, because the returned val is the same in both cases. (Of
course I added getopt.h to AC_CHECK_HEADERS.)
BTW: does anybody have an idea why this acclaimed GLIBC2.2 of the Developer
Tools doesn't have getopt_long? Or is it an addition in Linux only, that is not
even "GNU standard"?
Ciao,
Roland
