to blitz 20001213, gcc version 3.0 20010604 compiles every source
file without a problem and all tests of the testsuite pass on
i686-pc-linux-gnu. All programs of the examples directory compile and
run successfully, as far as I can tell (no core dumps).   

I have been trying to compile blitz for a long time and this is the
first time that gcc can compile every single source file and that all tests
pass. 

Thank you for making this possible.

Hope this helps,

Peter Schmid
