Yes, that's the conclusion I arrived at, after I sent yesterday's
mail and went to bed - "oh no, it can't do anything, there is no cmocka
in that cross-compile environment". But I didn't want to get up again
just to send that followup mail ;-)

This would have been my next question "how do I build this?" :-)
... adapted to my build environment...
-- Installing: /home/gert/mingw/opt/include/cmocka.h
-- Installing: /home/gert/mingw/opt/bin/cmocka.dll
... then returning to openvpn & re-running configure, it will
still not find it :-(
checking for CMOCKA... no
configure: WARNING: cmocka.pc not found on the system. Unit tests disabled
... so, configure CMOCKA_CFLAGS/CMOCKA_LIBS it is...
checking for CMOCKA... yes
... but then trying to build the test drivers fails, and from the looks
of it, it's finding but not utilizing the cmocka lib...

*scratch head*
Need to debug this more tonight...
