-- This file is a component of FLORIST, an implementation of an Ada API --
-- for the POSIX OS services, for use with the GNAT Ada compiler and --
-- the FSU Gnu Ada Runtime Library (GNARL). The interface is intended --
-- to be close to that specified in IEEE STD 1003.5: 1990 and IEEE STD --
-- 1003.5b: 1996. --

-- It may seem that this mechanism should not be necessary, since the
-- errno value supported by the C-language interface is per-thread.
-- Unfortunately, that per-thread value may be overwritten by
-- implicit OS service calls that take place between the point an
-- exception is raised and the point that it is handled. For
-- example, if raising an exception involves calling longjmp(), the
-- longjmp() call may overwrite the previous errno value. Since this
-- mechanism does add overhead, we are making its use selectable, via
-- gnatprep.
