Hi Holger,

thanks for the report - I'm unsure why this has happened with the
tarball above - but I've created a new tarball:

  http://floppsie.comp.glam.ac.uk/download/c/gcc-10.2.0+gm2-20210503.tar.gz

which I've been build and install on Debian Buster amd64.  The compile
and link also worked:

$ gm2 --version
gm2 (GCC) 10.3.1 20210429
Copyright (C) 2020 Free Software Foundation, Inc.

PURPOSE.

$ cat hello.mod
MODULE hello ;

FROM libc IMPORT printf ;

BEGIN
   printf ("hello world\n")
END hello.
$ gm2 -g hello.mod
$ ./a.out
hello world
$ cat hello2.mod
MODULE hello2 ;

FROM StrIO IMPORT WriteString, WriteLn ;

BEGIN
   WriteString ("hello world") ; WriteLn
END hello2.
$ gm2 -g hello.mod
$ ./a.out
hello world

it would be interesting to see if this worked on your system?

Gaius
