	* make.adb (Start_Compile_If_Possible): Compute location of resulting
	ALI file in this procedure instead of after the compilation itself,
	since the current directory might have changed in between when using
	-j<n>.

	* osint.ads: Addded missing alignment clause.

	* adaint.c, adaint.h, osint.adb (__gnat_reset_attributes,
	__gnat_size_of_file_attributes): Rename reset_attributes and
	size_of_file_attributes.

2009-10-30  Javier Miranda  <miranda@adacore.com>

	* sem_scil.adb (Adjust_SCIL_Node): Add missing management of sequences
	of statements when searching for SCIL nodes.

2009-10-30  Tristan Gingold  <gingold@adacore.com>

	* gnatlink.adb, link.c: By default use shared libgcc on darwin.
