flock() would actually have worked, it uses two int's as parameters
(fd and cmd) since it's going to (un)lock the whole file. I've DDB'd
the problem and noticed that i've configured it to use fcntl() for
locking (it reports ``flock failed'' though), so the `struct flock'
taken by fcntl() is the real problem.

Never trust an operating system you don't have sources for. ;-)
