3) "A pragma is used to convey information to the compiler."  Use it
when you know something about the code that the compiler doesn't know.
In the case of case of pragma INLINE, this shouldn't happen very
often.  It might be appropriate for short library routines (such as
math vector operations) which you might expect to find in hot spots
such as inner loops.
  Generally, pragma ELABORATE (unit_you_want_inlined) followed by
pragma OPTIMIZE (time) in the calling unit is more appropriate.
