Have you read the documentation?  It clearly says you must not build
in the directory containing the sources.  You must do:

$ mkdir gcc-4.1.1.o; cd gcc-4.1.1.o
$ ../gcc-4.1.1/configure --prefix=/myLocation --enable-languages=c,c++,ada
$ make bootstrap

Do you have a previous version of GNAT installed?  Since GNAT is
written in Ada, you need an Ada compiler to bootstrap it.

What "make" command do you use, after the configure?  It should be
"make bootstrap" or "make bootstrap-lean".

The GNAT tools (gnatmake etc) should then normally appear in the gcc
subdirectory.
