 I have now tested Mark's fix for PR 8361 and while that does not affect
 non-optimizing performance, the difference for -O3 is noticable.
 
 Below are the results of the 3.3-branch from 03/15 versus 03/24 (without
 explicit --disable-checking):
 
   % \time /files/pfeifer/gcc-3.3-0315/bin/g++ -c generate.ii
        28.50 real        27.57 user         0.75 sys
   % \time /files/pfeifer/gcc-3.3-0324/bin/g++ -c generate.ii
        28.70 real        27.42 user         0.69 sys
 
 No difference for non-optimizing compilation...
 
   % \time /files/pfeifer/gcc-3.3-0315/bin/g++ -O3 -c generate.ii
       109.55 real       105.85 user         3.06 sys
   % \time /files/pfeifer/gcc-3.3-0324/bin/g++ -O3 -c generate.ii
        81.28 real        77.41 user         3.55 sys
 
 ...but a nice speedup for -O3!

 Is there any way, I can get the non-preprocessed code, because the  
 preprocess code produces errors in the system headers.

 Hi Gerald,
 
 Could you produce compile times for this PR and see how we're doing on 
 3.3 and
 mainline?  Quite a few speedup patches have gone in lately (most notably 
 the GC
 limits patches), so the numbers really are way outdated now...

 P.S.  Welcome back ;-)
