As I wrote earlier I packaged files that were installed by 'make install'

 From the other side we may be able to have LTO support in future. At least
I got it working with some days old snapshot from gcc trunk
(gcc 4.9.0 20131121). Required some porting though.

Here helped GCC debugging information related configuration update
(I tested it at first with snapshots from trunk before rebuilding gcc-4.8.2):
I was able to debug lto1.exe (size about 117 MB) in DOS session
under Windows Vista without problems. Without these updates
I would have serious trouble displaying backtrace in GDB.

The problem is that LTO support uses file names not acceptable
without LFN like '*.ltrans.out'. The situation even worse if
-save-temps command line option is being used as then I'm getting
file names like *.exe.ltrans.out, *.exe.ltrans0.o, *.exe.ltrans0.s.
So additional porting will be needed
