Subject: [ruby-talk:5174] Re: Compile Problem with 1.6.1

Well, just to see what would happen, I changed the Athlon optimisations
to PentiumPro optimisations, and it compiled fine. The make test still
fails:

[root@localhost ruby-1.6.1]# make test
not ok float 9 -- /downloads/ruby-1.6.1/sample/test.rb:562
test failed
make: *** [test] Error 1

(gdb) r ./sample/test.rb
Starting program: /downloads/ruby-1.6.1/miniruby ./sample/test.rb
warning: Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.

But otherwise, so far it seems to be working (altho' I haven't had time
to run more than a "Hello World" sort of app.......

Of course, it might be a good idea to try and make Ruby compile
successfully with AthlonGCC, in which case I'll volunteer to test
various things/patches/etc....
