Subject: configure.ac: simplify AC_CHECK_FUNCS statements
X-Git-Tag: v2.5_beta1~213
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=91d84530d7eb24718b99478ebac6ba40b0615b28;p=thirdparty%2Fopenvpn.git

configure.ac: simplify AC_CHECK_FUNCS statements

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.
