Run "autoheader" and it will update the include/htconfig.h.in , which
becomes htconfig.h which is #included in the code. You should get your
DEFINE set, and then you can #ifdef, #ifndef, etc.

Personally, if I don't have a system-level file-locking system, I'd
implement one in user code, say with a .lock file in the same directory
(if writable) or using TMPDIR and something like

$TMPDIR/path-to-file.lock

for locking /path/to/file.

I've actually felt this might not be a bad addition to the htdig code
anyway, since the databases really should be locked against multi-write
until they have granularity.

Does that make any sense?
