When I read this at first, I feared that you would change a
`pthread_init_mutex()` to using `PTHREAD_MUTEX_INITIALIZER` instead. On
the face of it, that would look good on paper, but it unfortunately falls
flat for us because there is no Win32 equivalent for the static
initializer: we emulate mutexes via `CRITICAL_SECTION`s, and those need to
be initialized by running a function.

To my surprise and relief, your patches do not do that; The only mutex in
`grep.c` (`grep_attr_mutex`) is not touched.

I just wanted to mention this here, in case anybody else had the same
idea.

Thanks,
Dscho
