At first I thought it did, but after going through some references I now  
don't think so.

I think I finally have the correct answer this time.

If you compile the original example, it "fails" just like the sample C++ 
program in bug #377 when ctrl-z is pressed. When a call to 
clearerr(stdin) is added as above, the program waits at the second 
prompt. But when I added clearerr(stdin) to bug 377's sample 
program, it made no difference. So I have to conclude that it's a 
libstdc++ and not a DJGPP problem .

BTW, forget my patch to filbuf since it's not correct.

Mark
