exp_dbug.ads, [...] (Get_External_Name): Add missing initialization of Homonym_Len.

2006-10-31  Robert Dewar  <dewar@adacore.com>

	* 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.
