This is a slightly improved version of the patch
http://gcc.gnu.org/ml/gcc-patches/2010-08/msg02065.html with Laurynas
comments from http://gcc.gnu.org/ml/gcc-patches/2010-09/msg00419.html
adressed.  As I told before, it improves the core
get_output_file_with_visibility function. This version (relative to
http://gcc.gnu.org/ml/gcc-patches/2010-08/msg02065.html I did sent
before) improved comments and function names, following Laurynas
advices; I also avoided calling regexec twice needlessly. I added a
lot of explanatory comments.  It is made much more modular and less ad
hoc by a file rule machinery. We now use regular expressions to match
the input file name and compute the associated output name & for name.

A detailed comment is available in the patch.
