The functions fnmatch(), getopt(), getentropy() and others are grouped into the standard Option Group POSIX_C_LIB_EXT. The getentropy() function is currently in-draft for Issue 8 as of 2021. https://www.opengroup.org/austin/docs/austin_1110.pdf Not surprisingly, the POSIX_C_LIB_EXT Option Group also includes the highly debated strnlen() function. Moving that function will be deferred until later. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>pull/73756/head

Group, consisting of fnmatch(), getopt(), getsubopt(), optarg, opterr, optind, optopt, |

stpcpy(), stpncpy(), strcasecmp(), strdup(), strfmon(), and strncasecmp(), strndup(), and |

strnlen(). |
