# 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.
