commit 1e3fc905b227741b6e96f8d9d11584555a424c50
Author: Stefano Lattarini <address@hidden>
Date:   Fri Nov 12 17:18:09 2010 +0100

    Tests required tools: also try `-v' option for GNU compilers.
    
    * tests/defs.in: In the loop on "$required" tools, for gcc
    and g++, also run "gcc -v" (resp. "g++ -v"), to get more
    information, and for consistency with gcj.
