[RFA] Fix an error in value_change_enclosing_type

[Pierre Muller <muller@ics.u-strasbg.fr>]

the function value_change_enclosing_type
does not set the enlclosing_type field correctly if
the new_encl_type has a bigger length that the value type.

Its seems quite astonishing that this has not been noticed before, 
but I discovered it when trying to get 
the fpc-abi.c code to work correctly.

ChangeLog entry:

2002-10-07  Pierre Muller  <muller@ics.u-strasbg.fr>

        * values.c (value_change_enclosing_type): Set 
        enclosing_type field correctly also for the case where 
        more memory needs to be allocated.
