 Me neither.  But it does worry me if interfacing to C is appropriate
too often.
 Multi-language projects are more work to maintain.  C (or special OS
calls) are less portable.  It's hard to argue strongly for Ada while
also saying "except for the parts Ada can't do well" (even if that
really means except for the parts this particular Ada compiler doesn't
do well).  And consider the start of this discussion:  someone
translated a small program from C to Ada and found it ten times
slower.  I don't know what happened in that particular case, but often
that sort of thing results not in investigation of how to get around
the weak points of the Ada compiler/library, but rather in non-use of
Ada because "Ada is ten times slower".
  There should be *very* few cases where C is the more appropriate
language.
