Hi,
experiencing configure problem
./configure: line 18777: ac_fn_c_try_run: command not found
It seems that CMU_HAVE_OPENSSL brings CMU_FIND_LIB_SUBDIR brings
AC_CHECK_SIZEOF(long) ... that brings the use of *check_int and that
brings the use of ac_fn_c_try_run ... but it doesn't bring the macro
defining it.
But since AC_CHECK_SIZEOF is working fine, it seems like something else confuses
it and makes that macro think that `ac_fn_c_try_run` is already defined.
IMO there's something wrong with calling AC_TRY_RUN in AC_CACHE_VAL.
Poking at NEWS:
*** Many macros no longer AC_REQUIRE as many other macros as they used to.
This can expose several classes of latent bugs. These are the ones
we know about:
- Make sure to explicitly invoke all of the macros that set result
variables used later in the configure script, or in generated
Makefiles.
- Autoconf macros that use AC_REQUIRE are not safe to use in shell
control-flow constructs that appear outside of macros defined by
AC_DEFUN. Use AS_IF, AS_CASE, etc. instead. (See the
“Prerequisite Macros” section of the manual for details.)
The set of macros that use AC_REQUIRE internally may change from
release to release. The only macros that are guaranteed *not* to
use AC_REQUIRE are the macros for acting on the results of a
test: AC_DEFINE, AC_SUBST, AC_MSG_*, AC_CACHE_CHECK, etc.
- AC_REQUIRE cannot be applied to macros that need to be used with
arguments. Instead, invoke the macro normally, with its arguments.
Can you please investigate this ?

Thanks.
