I do not kmow anout the error messages but here are some tips I 
have found.

The version of gcc installed in the system should be same or very 
close to the source code. So install the newest package available.

Everything seems to work if we want the c compiler only. Trouble 
begins when we want more. It is better to start with only c 
compiler (--enable-languages=c). When this is made and installed 
correctly then it may be possible to compile other languages.

The full build process first makes a compiler and then tries to 
compile itself again with this new compiler. For me this seems to 
fail more often than not. For cross compilers this is not 
possible at all. The option --disable-bootstrap omits this last 
stage.
