This macro tries to find strcasecmp() in string.h.
Use this macro in conjunction with ETR_STRINGS_STRCASECMP in your
configure.in like so:
ETR_STRING_STRCASECMP
if test x"$ac_cv_string_strcasecmp" = "xno" ; then
ETR_STRINGS_STRCASECMP
fi
This will cause either HAVE_STRING_STRCASECMP or
HAVE_STRINGS_STRCASECMP to be defined in config.h, which will tell
your code what header to include to get strcasecmp()'s prototype.
AC_DEFUN([ETR_STRING_STRCASECMP],
[
AC_CACHE_CHECK([for strcasecmp() in string.h], ac_cv_string_strcasecmp, [
AC_TRY_LINK(
[ #include <string.h> ],
[ strcasecmp("foo", "bar"); ],
ac_cv_string_strcasecmp=yes,
ac_cv_string_strcasecmp=no)
])
if test x"$ac_cv_string_strcasecmp" = "xyes"
then
AC_DEFINE(HAVE_STRING_STRCASECMP, 1,
[ Define if your system has strcasecmp() in string.h ])
fi
]) dnl ETR_STRING_STRCASECMP
