Now I finish development of Win64 GUI for a call of the Gromacs commands. 
It uses well structured help of Gromacs utilities for dynamic creation of modeless dialog boxes 
for a choice of parameters of a commands and then commands execution. 
It is implemented by non-blocked I/O redirection of gmx I/O through named pipes.
The main problem which I taked - The commands in interactive mode of user interaction hungs up, 
so without showing anything in the pipes. After some time of dances with tambourines (debugging),
I understood that faults caused by buffering of stdout/stderr, 
the problem was solved by adding of fflush (stdout/stderr) before an interactive call of fgets (., stdin).
In this regard I have any questions to developpers: 
- whether it makes a sense to add correction to a repository or it is better to make it to authors of a code?
- why such disorder with use of stdout and stderr in sources?
List of files witsh adding fflush:
And may be anything else?
