Hello Jiří,

I think this question should be directed at gcc-help@gcc.gnu.org.
Please send any response to this email there.

Quoted from http://gcc.gnu.org/install/configure.html:

    we highly recommend that GCC be built into a separate directory from
    the sources which does not reside within the source tree.

I guess you should try to use a build directory separate from the
sources and follow closely the instructions on the link above.
