Weird... You can substitute isspace here anyway.  I'll do that since
isspace is in ANSI C, isblank is ISO.

Yes, make is like that...

I will one day remove that toplevel target.  There's really little point
in compiling every single module, unless you're testing.  And putting them
into a single library like it does is doubly silly: symbols clash all
over the place (eg. tdb and tdb2!).

Meanwhile, make -k, or blow away tdb2, or add it to EXCLUDES= in the
Makefile.

Great!  Just copy another module, and run ccanlint.  Any questions please
ask here...

Cheers,
Rusty.
