After a lot of googling and experimenting, I think I have managed to
make it work, but only in C code, and I want it to run in Pascal. The
key to make it work in C was to call setvbuf at the right time, to set
the buffering mode for stdin/stdout. The problem with FPC is that I
can't find any straightforward way to either get PFile-style
stdin/stdout from the Text-style input/output (surely there is a
connection?)
Yes. PFile _IS_ Text style. PFile is the C wrapper implementing buffer,
Text the analogue Pascal buffering. I assume that settextbuf to 0 didn't work?

If that doesn't work, you need to go back to the raw unbuffered IO, do a
IOCTL if necessary. FPOpen, FPClose, FPWrite, FPRead
Moreover, how does lazarus deal with this?
I guess Lazarus doesn't care, as long as it gets all the information at
the end. There is no bidirectional communication between Lazarus and the
compiler.
