The enclosed patch adds support for nanosecond timestamps on *BSD
systems.
Since *BSD uses st_mtimespec and Solaris uses st_mtim, this required
AC_STRUCT_ST_MTIM_NSEC to pass the toplevel field name instead of just
tv_nsec (or equiv).

* acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add support for *BSD's
st_mtimespec field.
* filedef.h (FILE_TIMESTAMP_FROM_S_AND_NS): Likewise.
