new gm2-10.2.1 package available for buster and raspbian

[Gaius Mulley]

Hi,

I thought I'd mention that there are new gm2 packages for amd64 (Debian
Buster) and Raspbian available from floppsie.comp.glam.ac.uk

https://www.nongnu.org/gm2/debian.html

change stretch for buster, I'll be updating the documentation as well.

The bugfix which flushed the new package caused a bootstrap problem (mc
would no longer bootstrap itself).  It manifested itself when a string
was used both in a call to a C function and also to a Modula-2
procedure.  For example:

printf ("\n");
WriteString ("\n");

would break as the string \n would be converted with escape sequence
applied - the same string would be incorrectly passed to the Modula-2
WriteString.  Anyway this is now fixed on master and the 10 branch.
Internally gm2 keeps track of 4 different kinds of string:

  Modula-2 string "abcde \n"    (no escape applied and no trailing nul)
  Modula-2 string "abcde \n"    (no escape applied and with trailing nul
  used during unbounded array and array assignment if there is room)
  C string "abcde \n"           (escape applied and no trailing nul)
  C string "abcde \n"           (escape applied and trailing nul used
                                 for printf and friends)

In other news there was a virtual GCC summit which was pretty
interesting as GDB will be supporting dwarf5 (work in progress).  Dwarf5
gives us SET type debugging and MODULE scoping and also WITH scoping.
