Hi Etienne,

I get them with debugging-features enabled:

./configure --enable-debugging-features --prefix=$HOME/local/staging

And the warnings:

 gcc -DHAVE_CONFIG_H -I. -I. -I../../src/include -I./include -I./inlinability -Iinlinability -DBOOT_CLASS_PATH=\"/home/david/local/staging/share/sablevm-classpath:/home/david/local/staging/share/sablevm-classpath/libclasspath.jar:/home/david/local/staging/share/sablevm-classpath/resources.jar\" -DBOOT_LIBRARY_PATH=\"/home/david/local/staging/lib/sablevm-classpath\" -g -O2 -Wall -fno-gcse -fno-strict-aliasing -std=iso9899:1990 -pedantic -Werror -O0 -W -fno-builtin -Wshadow -Wpointer-arith -Wbad-function-cast -Wundef -Wcast-align -Wwrite-strings -Wsign-compare -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Wno-long-long -MT libsablevm.lo -MD -MP -MF .deps/libsablevm.Tpo -c libsablevm.c  -fPIC -DPIC -o .libs/libsablevm.o

I didn't find a solution yet but I think it is specific to gcc 3.4 from
what I found on the web.
