Things which should be considered:

* with gperf v.s. without gperf

* ./configure v.s. …/ruby/configure

* GNU make v.s. HP-UX make # HP-UX make invokes the action if lex.c

and keywords has same mtime.

* svn checkout generate a file with mtime as current time

* XFS has a mtime with fractional part
