* env.c (__gnat_environ): return NULL for vThreads - unimplemented

* sem_disp.adb (Check_Direct_Call): New routine. Dispatching calls
where the controlling formal is of private class-wide type whose
completion is a synchronized type can be converted into direct calls.
2009-06-21 Vincent Celier <celier@adacore.com>
* gnatcmd.adb (Check_Files): When all sources of the project are to be
indicated to gnatcheck, gnatpp or gnatmetric, always specify the list
of sources using -files=, so that the distinction can be made by the
tool of a call with no source (to display the usage) from a call with
a project file that contains no source.

* exp_ch3.adb (Build_Array_Init_Proc): Do not build the init proc in
case of VM convention arrays.
