Functioning GCC - yes. GCC functioning as a cross-compiler - NO!

Not, unless one spends a few days writing in this mailing list until it 
becomes clear that a couple of additional *GCC* packages need to be 
installed for GCC to function as 'advertised', i.e. with the 
cross-compilation working.

Right from the start Andrew have said that GCC, by default, when 
installed, is cross-compiling. That, clearly, is not the case as I 
already pointed out on numerous occasions. If you think that it is, then 
keep dreaming and best of luck!

Besides, I am not at all interested in getting '64-bit-only' compiler - 
that is not the purpose I started this thread. I am interested in 
getting a cross-compiler. To me the term 'cross-compiling' means to be 
able to compile binaries for more than one architecture (i686 and x86_64 
in my case).

They way things are at present, GCC, as installed by Fedora, does NOT 
cross-compile, despite what you, Andrew, John Doe or whoever else may 
claim. It may be a '64-bit-only' compiler, yes, but certainly isn't a 

Secondly, if I want to build GCC purely from source as a cross-compiler 
(yes, from source - without using additional binaries from the same 
package) using the gcc.spec file I can't - not without extensive editing 
and messing about with the said file and even then I would still need to 
install additional GCC binaries (binaries from the same group of 
packages I am trying to build, no less!) in order to make the whole 
thing work!

If you, Andrew or anyone else think that's OK - well, keep deluding
