It points to /usr/bin/cpp, a native cpp from the compiler used.

I installed glibc in /usr up to and including version 2.2.4. Everything
was all right.

By the way, could it be a kernel issue? execv is (I suppose) a very
much kernel thing...


I configured glibc with the following:

export CFLAGS="-O2 -march=i686 -mcpu=i686"
export LDFLAGS='-Wl,-O2,--enable-new-dtags'

./configure --prefix=/usr --with-headers=/usr/src/linux/include \
        --enable-add-ons=yes --disable-cvs --disable-debug \
        --disable-profile --with-gd-include=/usr/include \
        --with-gd-lib=/usr/lib --enable-kernel=2.4.0 --with-elf
