When compiling glibc-2.3.3 (configured from a new subdir "obj" using simply ../configure --enable-add-ons), I get the following error message in glibc subdirectory "elf". The problems seems to be a gcc bug, since gcc-3.3.4 compiles fine (and since I could not really see why the types should conflict).
