# =========================================================================== # https://www.gnu.org/software/autoconf-archive/ax_string_strcasecmp.html # =========================================================================== # # SYNOPSIS # # AX_STRING_STRCASECMP # # DESCRIPTION # # This macro tries to find strcasecmp() in string.h. # # Use this macro in conjunction with AX_STRINGS_STRCASECMP in your # configure.in like so: # # AX_STRING_STRCASECMP # if test x"$ac_cv_string_strcasecmp" = "xno" ; then # AX_STRINGS_STRCASECMP # fi # # This will cause either HAVE_STRING_STRCASECMP or HAVE_STRINGS_STRCASECMP # to be defined in config.h, which will tell your code what header to # include to get strcasecmp()'s prototype. # # LICENSE # # Copyright (c) 2008 Warren Young <warren@etr-usa.com> # # Copying and distribution of this file, with or without modification, are # permitted in any medium without royalty provided the copyright notice # and this notice are preserved.
