Hi,
I am using the stable snapshot of ruby, which I downloaded today
(version.h stated it is the verison 2004-07-01)
I build it with
export CFLAGS="-O3 -march=athlon-xp -mcpu=athlon-xp -mfpmath=sse -funroll-loops -fforce-mem -fforce-addr -finline-functions -malign-functions=4 -mpreferred-stack-boundary=2"
export CXXFLAGS=$CFLAGS
./configure --prefix=/usr --enable-shared --disable-static && \
make && make test && sudo make install
which never fails.
Until now...
make quits with:
ar rcu libruby-static.a array.o bignum.o class.o compar.o dir.o dln.o enum.o error.o eval.o file.o gc.o hash.o inits.o io.o marshal.o math.o numeric.o object.o pack.o parse.o process.o prec.o random.o range.o re.o regex.o ruby.o signal.o sprintf.o st.o string.o struct.o time.o util.o variable.o version.o dmyext.o

Then I tried to unset all CXXFLAGS and CFLAGS.
This time make fails with:
gcc -g -O2 -fPIC -rdynamic -L. main.o -lruby -ldl -lcrypt -lm -o ruby

Both works without problems in all previous versions of ruby.
gcc is of version 3.3.4
How can I avoid this problem ?
Thank you very much in advance for any help ! 
Let's ruby!
