Tested on i686-linux, committed on trunk.

The problem here was with external symbols whose fully
qualified names were identical due to the fact that they
lived within anonymous blocks, and there was a kludge
in exp_dbug.adb to eliminate names of anonymous blocks
from fully qualified names.

This kludge just does not work. It was already being
bypassed for init routines where we had previously
discovered this, but that's not good enough.

The kludge is there solely for the benefit of the
debugger, which cannot easily deal with attempts to
view such variables with their qualified names.

But really this is because such names cannot be
viewed in Ada terms given the anonymous blocks.

The limitations of the debugger are much less important
than making sure that legal Ada programs compile properly.

We couldn't come up with a simple example test program unfortunately.

	* exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
	initialization of Homonym_Len.
	(Fully_Qualify_Name): Remove kludge to eliminate anonymous block
	names from fully qualified name. Fixes problem of duplicate
	external names differing only in the presence of such a block name.
