Thanks, installed.

Right.  The code now AC_COMPILE_IFELSE, so it should be fine.  The
autoconf manual says AC_TRY_COMPILE is obsolete so I didn't want to use
it.  AC_TRY_COMPILE is used in many places in gnulib though, do we want
to care about that?  I find AC_TRY_COMPILE slightly easier to work with
than AC_COMPILE_IFELSE so perhaps we could argue that it should be
non-deprecated, unless there were a strong reason to deprecate it.
