Hi. 

This fixes a couple problems with the generated doxygen output. In
addition, it updates the generated doxygen config to 1.3.9.1, and
removes using dot in the default config. (This last bit is at the
longstanding request of the SC. Sadly, free software with equivalent
functionality of graphviz is still in progress. In the meantime, those
who want dot output will have to generate it themselves, which should
not be an undue hardship.)

The new output can be browsed here:

http://gcc.gnu.org/onlinedocs/libstdc++/latest-doxygen/index.html

I posted archives of generated html and man pages here:

tested x86/linux
