[PATCH] gm2: fix bad programming practice identifier warning

[Wilken Gottwalt]

Fix using keywords as identifiers to prevent warnings coming from
Modula-2's own libraries.

m2pim/DynamicStrings.mod:1358:27: note: In procedure ‘Slice’: the symbol
name ‘end’ is legal as an identifier, however as such it might cause
confusion and is considered bad programming practice
 1358 |    start, end, o: INTEGER ;

m2pim/DynamicStrings.mod:1358:27: note: either the identifier has the
same name as a keyword or alternatively a keyword has the wrong case
(‘END’ and ‘end’)

gcc/gm2:
        * gm2-libs/DynamicStrings.mod: Fix bad identifier warning.
