Hi,

This is actually a patch for symtab/12704, reported by Jan:

(gdb) b 'FOO::(anonymous namespace)::BAR()'
Junk at end of arguments.


This is happening because along with the physname patch, there was also 
alot of mucking around with decode_line_1 and decode_compound. This is 
fallout from that. [Remember: we used to push almost everything through 
decode_variable -- in which the quoting is /required/.]

If we see "(anonymous namespace)", we must keep it as a significant part 
of the name. On the upside, we now no longer have to quote this stuff, 
either.

This patch also contains one cleanup. The string "(anonymous namespace)" 
was beginning to proliferate throughout the sources. I've added a macro 
to cp-support.h to define this string and changed all the places it had 
been hard-coded.

Tested on the buildbot.

Keith
