Bison sync with Automake 1.8 (config/depcomp, config/install-sh)

[Paul Eggert]

I applied the following changes from Automake 1.8 to Bison.  (Does
anybody know why we can't simply remove the files, and let 'bootstrap'
make them?)

2003-12-23  Paul Eggert  <address@hidden>

        * config/depcomp, config/install-sh: Sync with Automake 1.8.
