	* binde.adb (Elab_All_Links): Remove unnecessary call to
	Generic_Separately_Compiled (if a unit satisfies this predicate, there
	won't be an associated Afile).
	(Elab_All_Links): Fail if a referenced unit cannot be found

	* bindgen.adb:
	Fix comments in bindgen regarding consistency checks done in Bcheck:
	the checks are made across units within a partition, not across several
	partitions.
	Fix generation of C binder file for VxWorks.

	* lib.adb (Generic_Separately_Compiled): Rename to
	Generic_May_Lack_ALI, more descriptive of the current use of the
	predicate, and update documentation.

	* lib-writ.ads, lib-writ.adb (Write_With_Lines): Minor code
	reorganization and documentation update for the case of predefined
	library generics (for which we do not reference an Afile).
