Duncan,
Sorry, I couldn't get back to you sooner - had a real emergency at work.
My Linux distribution is Gentoo Linux. I've check that scandir is declared
in dirent.h. The scandir/scandir64 functions have the following declaration
there:
extern int scandir (__const char *__restrict __dir,
struct dirent ***__restrict __namelist,
int (*__selector) (__const struct dirent *),
int (*__cmp) (__const struct dirent **,
__const struct dirent **))
__nonnull ((1, 2));
The dirent.h file belongs to glibc. My glibc version is 2.10.1, the latest.
IMHO, the scandir function declaration has changed in new glibc. The
glibc-2.5 used in RHEL-5.2, however, declares that function as:
extern int scandir (__const char *__restrict __dir,
struct dirent ***__restrict __namelist,
int (*__selector) (__const struct dirent *),
int (*__cmp) (__const void *, __const void *))
__nonnull ((1, 2));
So, in order to make it compile we gotta distinguish the GLIBC versions.
