* include/features.h: If no feature selection given and we select
by default a POSIX mode, also define __USE_POSIX_IMPLICITLY. * posix/Versions: Export __posix_getopt. * posix/getopt.c (_getopt_initialize): Take additional parameter. Use it to alternatively initialize __posixly_correct. (_getopt_internal_r): Take addition parameter. Pass on to _getopt_initialize. (_getopt_internal): Take addition parameter. Pass on to _getopt_internal_r. (getopt): Pass additional zero to _getopt_internal. (__posix_getopt): New function. * posix/getopt.h: Add redirection for getopt. * posix/getopt1.c (getopt_long): Pass additional zero to _getopt_internal. (getopt_long_only): Likewise. (_getopt_long_r): Pass additional zero to _getopt_internal_r. (_getopt_long_only_r): Likewise. * posix/getopt_int.h: Adjust declarations of _getopt_internal and _getopt_internal_r.
