- dnl way, #ifndef _SYS_CDEFS_H may be used to include <sys/cdefs.h> both when
- dnl it has been checked for via the GNULIB configure test and found and when
- dnl it has not been checked for, which we can presume means that the <glob.h>
- dnl GNULIB shares with GLIBC is being included as a system header and not as
- dnl part of GNULIB, in which case <sys/cdefs.h> may be assumed.
- if test $SYS_CDEFS_H = no; then
- AC_DEFINE(_SYS_CDEFS_H, 1,
