#844 gen gcc: C code conflict between array-descriptor/UDT structures when declared/used inside successive scopes

[fxm (freebasic.net)]

At least 2 bug configurations have been highlighted:

1: Conflict in the emitted C code between the array descriptor structures when arrays are declared inside successive scopes.

2: Conflict in the emitted C code between local UDT structures (same UDT name) + instances when declarations are inside consecutive scopes.

A double scoping fixes the problem.

For more details and code examples (bug, and no bug with workaround), see on forum at posts:
