Changes.rst: Mainatiner update on C99

Mention for maintainers that we've moved to build with -std=c99 by
default.  Also document that 32-bit RHEL5 builds will need -std=gnu99
to be buildable.

 - Linux distributions using systemd is highly encouraged to ship these new unit

+- With OpenVPN v2.4, the project have moved over to depend on and actively use
+  the official C99 standard (-std=c99).  This may on some older compiler/libc
+  headers combinations fail.  On most of these situations it is recommended to
+  do use -std=gnu99 in CFLAGS.  This is known to be needed when doing
+  i386/i686 builds on RHEL5.
