	* sem_ch4.adb (Analyze_Allocator): Detect an allocator generated
	by the build-in-place machinery where the designated type is
	indefinite, but the underlying type is not. Do not emit errors
	related to missing initialization in this case.

2012-03-19  Robert Dewar  <dewar@adacore.com>

	* gnat_ugn.texi: Add documentation for -gnateinnn switch.
	* sem_elab.adb, put_alfa.adb, lib-xref-alfa.adb: Minor reformatting.
	* sem_prag.adb: Minor comment update.
