  This option can be used in FreedBSD with devel/libinotify
installed.

Detect presence of libinotify with pkgconf and use its word
to compile and link.

 v3: use _CFLAGS from pkgconf to get include dir

 v2: use _LIBS from pkgcong instead of hardcoded -linotify

We're getting close :-) - but something is still funny.  In the output,
I now have...

checking for OPTIONAL_INOTIFY... yes
../openvpn/configure: ,: not found
checking for CMOCKA... yes


... which is caused by these lines in configure:

------- snip ----------
                                        $as_echo "#define HAVE_SYS_INOTIFY_H 1" >>confdefs.h
,

$as_echo "#define ENABLE_ASYNC_PUSH 1" >>confdefs.h
------- snip ----------

so yes, there's a single line with a "," on it...  autoconf 2.69_3


It compiles and links fine, with inotify, but I think we should do a v4
and get rid of the Comma.

thanks,

gert
