It is strongly recommended against to parse the compiler output, as it is 
designed for humans, not computers. The formatting of the compiler output 
can therefore change in time and can also be configured by the user in any 
language. Some people are doing it anyway, like Lazarus.

The compiler has an interface designed for computers and that is through 
the compiler and comphook units. This allows you to retrieve the messages 
neatly. If you want process separation, please write a wrapper that puts 
the messages in a computer friendly way, and we'll include it in FPC.

About flushing the output, I think it is impossible to receive the output 
interactively currently, it will output in bursts. You should still be 
able to receive the output, though. If you want to receive it 
interactively, I think we can modify the compiler to flush after each 
message. But again, I do not recommend this approach.
