I guess vanilla autoconf does not have a generic macro
to check the availability of the options. For example,
the availability of "-g", "-std=XXX" are implemented
without simple public macros.

For detail, please check /usr/share/autoconf/autoconf/c.m4.
_AC_C_STD_TRY is an internal-but-generic macro to check
"-std=XXX" availabilities. It will be something useful to
check -mXXX availabilities.
