This is... interesting.  The change is minor, but seems to have pushed the
endless if/else if/else construction in options.c over an invisible cliff,
and some buildbots (FreeBSD 7.4, Debian 8.5) now *sometimes* bomb with
"signal 11" when gcc is compiling options.c ...

  gcc -DHAVE_CONFIG_H -I. -I../.. -I../../include  -I../../include  
-I../../src/compat           -DPLUGIN_LIBDIR=\"/usr/local/lib/openvpn/plugins\" 
 -g -O2 -std=c99 -MT options.o -MD -MP -MF .deps/options.Tpo -c -o options.o 
  gcc: Internal error: Killed: 9 (program cc1)
  Please submit a full bug report.
  See <URL:http://gcc.gnu.org/bugs.html> for instructions.

dmesg points to "too much stuff running on that box"

pid 91411 (cc1), uid 1000, was killed: out of swap space

(it's not a general problem - I can compile options.c just fine on f7.4,
but buildbot failed...)

So - if you bump into this, give your system more RAM.  This particular
VM has 512M RAM and *no* swap, seems this is not enough anymore.

Besides this, I don't think we need to do anything about it - except
document this here, so google can find it.


PS: and yes, I know that FreeBSD 7.4 is more ancient than the dawn of
time, but for some reasons I've become fond of it - "my first buildbot!" -
and it's well firewalled off the public Internet...  and it's sort of
my "how far back will it still work?" test.  If we break it, and for good
reason, it will be the XP/Vista thing - I'll try to not break it, but
if there is reasonable API changes that we want to have, goodbye.

now what should I write here...
