pragma Preelaborate_05 [(library_unit_NAME)];
This pragma is only available in GNAT mode (-gnatg switch set)
and is intended for use in the standard run-time library only. It has
no effect in Ada 83 or Ada 95 mode, but is
pragma Prelaborate when operating in later
Ada versions. This is used to handle some cases where packages
not previously preelaborable became so in Ada 2005.
