I compiled the following program with the Windows port of gfortran. When I run it in a MinGW shell, I do not see the output of the PRINT statement until after the READ statement has been executed. The problem does not exist if the program is run in a Cygwin shell, or in a DOS Window.
PROGRAM test CHARACTER :: ch PRINT *, "In the MinGW shell you will not see this prompt until after the READ" READ *, ch END PROGRAM test -- Summary: Is screen output buffered when gfortran is run in a MinGW shell?
