R devel - Nov 2004 - warnings(), last.warning, and libraries (PR#7363)

1) If warnings are generated during the installation of a library, the
'last.warning' object is retained in the environment.  

2) Since the warnings() does not explictly look in the .GlobalEnv for the
object it will find 'last.warning' objects in attached namespaces.  

--> Warnings from package instalation time can be reported at other times.

Easy solution: change the definition of warnings() to look in .GlobalEnv
explicitly.
