Hello plaisthos,

I'd like you to do a code review.
Please visit

    http://gerrit.openvpn.net/c/openvpn/+/453?usp=email

to review the following change.


Change subject: configure.ac: Remove unused AC_TYPE_SIGNAL macro
......................................................................

configure.ac: Remove unused AC_TYPE_SIGNAL macro

Recent autoconf warns:
configure.ac:448: warning: The macro `AC_TYPE_SIGNAL' is obsolete.

And it turns out that we do not actually use RETSIGTYPE.
Additionally, there is no reason to do so since as the
autoconf documentation says:
"These days, it is portable to assume C89, and that signal
handlers return void, without needing to use this macro or
RETSIGTYPE."
