I had to backport patches to be able to build ECL at revision
880259cb5533913a6c09d6c99d8d and some previous ones between
880259cb5533913a6c09d6c99d8d and released version 12.2.1, I hope I did
this right and 880259cb5533913a6c09d6c99d8d is indeed the culprit, but
the commits I imported back mainly concern functions involving
directories management and the conditional definition and use of
SPINLOCK depending on ECL_THREADS in very few places, so it looks ok.
