The use in glob.c conflicts with the definition in glibc, so #undef is
needed, not #ifndef. glibc has:
/* This is the data type of directory stream objects.
The actual structure is opaque to users. */
typedef struct __dirstream DIR;
extern int dirfd (DIR *__dirp) __THROW __nonnull ((1));
What works in a glibc build is this:
# undef dirfd
# define dirfd(str) __dirfd (str)
