It required a google search to find the installation instructions, 
pointing me to http://gcc.gnu.org/install/

I really think a link to that page should be part of either the README 
file on top of the source directory, or of the INSTALL/README file! Or you 
might provide a plain text version of the installation instructions in the 
sources --- probably in one of these README files.

Anyway. Assume that it really was a mistake to do "./configure" and  
"make" in the source directory.

I removed the old source (= old object) directory after saying "make 
distclean", unpacked the sources again, created a _different_ object 
directory (not a subdirectory of the sources), did configure there, and 
said "make". This is how i understood the installation instructions.

But still, the building did not finish successfully.

As before, it complains that it can't find stubs-32.h
The last words are like that:

In file included from /usr/include/features.h:346,
                 from /usr/include/stdio.h:28,
                 from /usr/local/gcc-4.2.1/gcc/tsystem.h:90,
