GCC-3.4.5 status report

[Gabriel Dos Reis <gdr at integrable-solutions dot net>]

Hi,

  Despite a number of bug fixing patches applied to gcc-3_4-branch
(special thanks to Richard Sandiford), the total count of bugs open
against GCC-3.4.5 only has increased from 115 (last report) to 117
(this morning).  That reflects a continual flux of incoming PRs for
GCC-3.4.x and bugs present in 3.4.5, 4.0.x and 4.1.x fixed in the
last two branches but not in 3.4.x.  As ever, the C++ front-end is the
winner of the usual contest.
