Subject: [svn-r5302] Purpose:     Configuration improvements

Description:
    Added more warning flags to gcc builds, especially with gcc 3+.  Also, added
    the -Wno-long-long flag to gcc builds to turn off the annoying "long long"
    warnings.

Platforms tested:
    FreeBSD 4.5 (sleipnir) with gcc 2.95.3 and gcc 3.1 (prerelease)
