Attention is currently required from: plaisthos.

Hello plaisthos,

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

    http://gerrit.openvpn.net/c/openvpn/+/674?usp=email

to review the following change.


Change subject: configure: Review use of standard AC macros
......................................................................

configure: Review use of standard AC macros

- Increase required version to 2.60 since that is documented
  minimum version for AC_USE_SYSTEM_EXTENSIONS
- Remove obsolete macros AC_C_CONST and AC_C_VOLATILE. They
  are noops on every compiler we support.
- Add explicit call to AC_PROG_CC. We get this implictly as
  dependency of other macros, but it is nicer to have it
  explicitely as well.
- A few typo and whitespace fixes.
