I think this is because in terminal Vim, Vim doesn't know what's
happening during the commands, so it assumes each command has filled the
screen and stops for you after each one so you can at least see the tail
output of each. But in GVim, the output goes through GVim itself, so it
knows when the screen is full; it can display the more prompt as well as
the press enter prompt exactly as many times as needed to ensure you see
all the output.

Do you need to see the output? If not, maybe :silent would help? It will
suppress the prompt altogether. (In my terminal Vim the screen is messed
up after doing this, though, and I need to issue :redraw to fix it up.)

If you do need the output, maybe you need to use a function that
captures the output or redirect it to a temporary file and read that,
and then display it the way you want it, rather than just using :! which
is simpler but not as flexible.
