Summary: no it isn't, yacc creates it

I had the same problem, but the workaround is very simple. y.tab.h is a
file generated by yacc. This means that what really needs to happen is
for yacc to be run before anything that #include's y.tab.h is
compiled.  One way to do this is to add y.tab.h to the list of things
that watcher depends on, like this:
    watcher: y.tab.h $(OBJS)
or something like that (I've forgotten exactly what the fix was).  If
all else fails, try running the yacc step manually, and then running
make again.

BTW, I reported this to watcher's author (Kenneth Ingham,
ingham@charon.unm.edu) and he tells me that the makefile worked fine on
his system as it was distributed. Make does things a little differently
between systems sometimes, so that a deficient makefile might work fine
on some systems and bomb on others. Note I said 'deficient' - I believe
that the distributed makefile really should have included watcher's
dependency on y.tab.h.
