Bug fix from SRC:
|
|
bug assigning arrays
|
|
|
|
This patch applies to all platforms.
|
|
|
|
The Modula-3 language definition says that it is possible to assign
|
|
one array to another if they have the same shape. There is a bug
|
|
in the compiler front-end that causes the compiler to report that
|
|
two array types are not assignable if they have different base
|
|
indices, even if they have the same size.
