Hi,
I've compiled Octave-2.1.60 with gcc-3.3.3 successfully, but the
performance is pretty bad with gcc-3.3.3.
The performance should of Octave is much better, when compiling it with
gcc-3.2.x instead.
The reason might be that the memory allocator on gnu stdc++ has changed to
one which is several times slower,
and therefore gives horrible performance on gcc-3.3 and gcc-3.4.
Therefore it would be nice to have gcc-3.2.2-3 to my cygwin.
So where can I find gcc-3.2.2-3 to my cygwin?
If you haven't built and tested the gcc of your choice on cygwin, how do
you know it performs better? What does the -3 mean in this context? Maybe
you're comparing performance between different platforms, or at least
different gcc targets.
