Hmm, sigh.  It was compiled on the latest (& only) version of Linux we have,
which is 0.99.14.  I'm not sure what to do about the FILE structure, if it's
unstable between releases.  We need to be able to do several non-std things:
   - set marks in a stdio stream and seek back to them, even if the
	stream comes from a pipe
   - test whether any data is available for reading on a stdio stream
   - read some data surrounding/preceding the read pointer in a stream buffer,
	for reporting syntax errors

GNU libc (which our version of Linux' stdio library, at least, is based on)
actually has c++ routines to set & seek to marks.  (I hope the interfaces to
those routines haven't changed in the current linux.)  There didn't seem to be
any blessed way to do the others, so it just peeks into the FILE structure.

Anyway, thanks for the fixes, Tim!
