OK, that's what I did now. I re-wrote the outputting of integers and reals
in Pascal now. So this program should work with the next GPC version.

However, especially the writing of reals has many special cases, so there may
be some bugs left. So please, everyone who's interested in this, write some
test programs, and submit them (!) -- preferably with (what you think are)
"special cases". It's better if the author doesn't do this himself because
he'll usually have handled those special cases that he thinks about...
