2009-04-20  Arnaud Charlet  <charlet@adacore.com>

	* opt.ads (Inspector_Mode): Update documentation of this flag.

2009-04-20  Thomas Quinot  <quinot@adacore.com>

	* g-socket.ads: Minor reformatting

	* socket.c, gsocket.h (__gnat_get_h_errno, VxWorks case): No need to
	consider S_resolvLib error codes since we only use the hostLib wrappers.

2009-04-20  Eric Botcazou  <ebotcazou@adacore.com>

	* sem_ch3.adb (Build_Derived_Private_Type): Insert the declaration
	of the Underlying_Record_View after that of the derived type.
