Aren't you supposed to have your build directory at the same level as your
source directory ? My directory setup for building a new gcc version is:

	/apps/gcc-<version>	(source directory)
	/apps/obj-gcc		(build directory)
	/apps/exe-gcc-<version>	(installed compiler)

I note that you are running gnatmake to get version information and not gcc
itself. Check to see if the Ada compiler on your system is invoked by gcc
or an alternative command like gnatgcc. Ie: do something like:

	gcc -c hello.adb

and see what the result is.

If your system uses gnatgcc for Ada programs, then try something like

	CC=gnatgcc ../<gcc_source_dir>/configure --enable-languages=c,ada ...

(BTW, I personally _always_ use --prefix to place the built compiler in it's
own location.)

Also, I can't remember if this version has dropped the requirement to issue a

	make gnatlib_and_tools

(I'm still using the 3.x series).
