GNAT/RTEMS 4.5.0 build error in bit_ada

[Dave Richards]

I am attempting to build GNAT/RTEMS from source on a Red Hat Linux 8.0
system (i386).  I have been working through the GNAT/RTEMS Getting Started
document, step by step, and am having trouble at the point of running the
bit_ada script.  It appears that the GNAT compiler resident in RH8.0 (which
identifies itself as gcc-gnat-3.2) is unable to build the cross-compiler.
The target I selected is i386, i.e.:

	./bit_ada i386

The build output is below.  Any ideas as to why this is happening?  I have
never succeessfully built GNAT from source either natively or as a
cross-compiler, so I'm a bit in the dark here.

	Thanks in advance!

	Dave
