GCC-3.3.3 first prerelease

[Michael Elizabeth Chastain]

I ran the gdb test suite with gcc 3.3.2, gcc 3.3.3-20040131,
and a recent gcc gcc-3_3-branch.

The debug info from gcc is fine for gcc 3.3.3-20040131 and gcc
gcc-3_3-branch.

This is limited to native i686-pc-linux-gnu, but I covered both
dwarf-2 and stabs+.
