Okay, here's the new version. Following Daniel's suggestion, it puts
symbols associated to DW_TAG_namespace in the symtab where they are
found, instead of in a special block, and creates one possible
namespace block for each objfile. This fixes the problem Daniel found
with the last version of my patch (which, incidentally, turns out also
to show up under DWARF 2 with pr-1210.exp; the more tests the
merrier).
Tested with GCC 3.2, i686-pc-linux-gnu with both DWARF 2 and stabs+,
and with a version of GCC 3.2.3 that generates DW_TAG_namespace DIEs.
No new regressions (though the new tests in gdb.c++/namespace.exp fail
under stabs+, as expected).
How does this one look to y'all?
