[Openvpn-devel] [PATCH] configure.ac: simplify AC_CHECK_FUNCS statements

[Lev S. <lst...@gm...>]

From: Lev Stipakov <le...@op...>

AC_CHECK_FUNCS checks availability of each function
in argument list and defines HAVE_function macro.
AC_CHECK_FUNC takes single function as an argument and
doesn't automatically define any macros.

When we check for availability of a single function and
define own macro, it is enough to use AC_CHECK_FUNC.
