Now that you mention it, I vaguely recall having to deal with that problem.

I _think_ the problem was that the code interfaced to a symbol in the GNAT
library called "c_constant_eof". As the Pipes package is a few years old,
GNAT has undergone several version upgrades since then, and that symbol is
no longer available.

Waitaminnit, oh, you are soooooo lucky!

I carry the DTraq code around with me on one of those flash memory drives,
and since it uses Pipes I pulled up the code.  Here's the comment I put in:

-- MODIFIED: 26 Jan 2003   Marc A. Criley
--    c_constant_EOF no longer available.  (Defined by GNAT 3.13p?  No
longer
--    available in 3.15p?)  Replaced with hard-coded -1, as per stdio.h

There you go!
