Yes, that seems to be true :

[root@localhost gmp]# grep FIB_TABLE_LIMIT *.h
fib_table.h:#define FIB_TABLE_LIMIT         47

But I would suspect the build in a subdir of the main GCC source
directory really could have any influence. In my case 'gcc-4.6.2/build'
was the equivalent to the 'gcc-4.6.2/objdir' here.

BUT what was totally different between my case and Me_Myself_and_I's
case was the choice for the "preferred build platform". Meanwhile
some really seem to trust to the achievements of the MS Company and
its leaders like Steve Ballmer who has referred to the free software
Linux kernel as a "cancer that attaches itself in an intellectual
property sense to everything it touches." 
(http://en.wikipedia.org/wiki/Steve_Ballmer) Once this same guy told us 
with Mr. Gates "MS
Xenix being the future in the 32-bit PC-world", ie their goal was to
create a commercial Unix for PCs which rules the whole Unix world...
Who believes, who not...

In any case the configure command for my "MinGW-targeted GCC on MinGW-
host" was :

../configure --build=i686-linux-gnu --host=i586-mingw32 \
--target=i686-mingw32 --enable-languages=c,c++,java \
--prefix=/opt/cross --libexecdir=/opt/cross/lib \
--disable-sjlj-exceptions --with-dwarf2 --enable-shared \
--disable-win32-registry --disable-nls \
--enable-libstdcxx-debug --enable-version-specific-runtime-libs \
--with-gxx-include-dir=/opt/cross/include/c++/4.6.2 \
--program-prefix=i686-mingw32- --program-suffix=-4.6

Using a different CPU name ('i686' instead of 'i586') made it to be a
crosscompiler, quite identical with the original Linux-hosted one, not
a different native GCC...

The '--enable-libgcj' would have been required in order to get libjava
but as everyone who has tried this knows, producing it doesn't work and
therefore its build for MinGW target is disabled as default in the
gcc-4.6.2 sources...

The $host GCC in the build was :

[root@localhost gcc-4.6.2]# i586-mingw32-gcc-4.6 -v
Using built-in specs.
COLLECT_GCC=i586-mingw32-gcc-4.6

gcc version 4.6.2 (by Kai Ruottu)

On Linux it succeeded nicely to produce gmp, mpfr and mpc from their
sources after making one fix in the used mpfr-2.4.2 sources, the
fixed code is the following :

    cygwin* | mingw* | pw32* | cegcc*)
      # When not using gcc, we currently assume that we are using
      # Microsoft Visual C++.
      # hardcode_libdir_flag_spec is actually meaningless, as there is
      # no search path for DLLs.
      hardcode_libdir_flag_spec=' '
      allow_undefined_flag=unsupported
      # Tell ltmain to make .lib files, not .a files.
      libext=a
      # Tell ltmain to make .dll files, not .so files.

Originally there was :

      # Tell ltmain to make .lib files, not .a files.
      libext=lib

which caused the mpc configure to not find a suitable 'libmpfr' :-(
The bug was in two places in 'mpfr-2.4.2/configure'...

Ok, here were hints for those who are going to create a MinGW-hosted
and MinGW-targeted gcc-4.6.2 on some sane build platform, not on
Windoze...

The error which I got when trying to get libjava was :

As the Me_Myself_and_I's case shows, it isn't that wise to start to
hit one's head against the wall in a garage which is not suitable
for building anything there, much better would be to find a better
place (like a nice small factory with working tools) where to build
things...
