These are simply the old replacement idioms that are not C++ safe.
We introduced the C++ safe idioms for most header files in March 2010,
but the old idioms are still used in a couple of places:
m4/eaccess.m4: [AC_DEFINE([eaccess], [access],
m4/fnmatch.m4: AC_DEFINE_UNQUOTED([fnmatch],
[${gl_fnmatch_required_lowercase}_fnmatch],
m4/getpass.m4: AC_DEFINE([getpass], [gnu_getpass],
m4/gettimeofday.m4: AC_DEFINE([gmtime], [rpl_gmtime],
m4/gettimeofday.m4: AC_DEFINE([localtime], [rpl_localtime],
m4/regex.m4: AC_DEFINE([re_compile_fastmap], [rpl_re_compile_fastmap],
m4/regex.m4: AC_DEFINE([re_compile_pattern], [rpl_re_compile_pattern],
m4/regex.m4: AC_DEFINE([re_comp], [rpl_re_comp],
m4/regex.m4: AC_DEFINE([re_exec], [rpl_re_exec],
m4/regex.m4: AC_DEFINE([regcomp], [rpl_regcomp],
m4/regex.m4: AC_DEFINE([regerror], [rpl_regerror],
m4/regex.m4: AC_DEFINE([regexec], [rpl_regexec],
m4/regex.m4: AC_DEFINE([regfree], [rpl_regfree],
m4/regex.m4: AC_DEFINE([re_match_2], [rpl_re_match_2],
m4/regex.m4: AC_DEFINE([re_match], [rpl_re_match],
m4/regex.m4: AC_DEFINE([re_search_2], [rpl_re_search_2],
m4/regex.m4: AC_DEFINE([re_search], [rpl_re_search],
m4/regex.m4: AC_DEFINE([re_set_registers], [rpl_re_set_registers],
m4/regex.m4: AC_DEFINE([re_set_syntax], [rpl_re_set_syntax],
m4/regex.m4: AC_DEFINE([re_syntax_options], [rpl_re_syntax_options],
m4/selinux-selinux-h.m4: AC_DEFINE([fgetfilecon], [rpl_fgetfilecon],
m4/selinux-selinux-h.m4: AC_DEFINE([getfilecon], [rpl_getfilecon],
m4/selinux-selinux-h.m4: AC_DEFINE([lgetfilecon], [rpl_lgetfilecon],
m4/strftime.m4: AC_DEFINE([my_strftime], [nstrftime],
m4/timegm.m4: AC_DEFINE([mktime], [rpl_mktime],
m4/tzset.m4: AC_DEFINE([tzset], [rpl_tzset],
Which of these modules are used by Octave?
