Sorry, but we're not speaking of contemporary developments, but choices
of implementation done 30 years ago, when GNU foundation was just
created, and when there was no internet network. It's very easy to make
good choices of implementation (usage of integer type etc.) for
actual developers, taking into account about errors of the past
programmers. But if today's programmers are correctly developing in
C language, that's because developers like me made errors in the past.
The problem is that programs like Eureka 2.12 are now obsolete. It
represents a large part of softwares developed on ATARI ST hardware.

You would have been very clever if you had given me those advices
30 years ago. For the time being, there's nothing else I can do,
except being very sad my C sources are not supported anymore, alas.

Thanks for your answer.

Regards,
