[PATCH] Correct pascal parser problem.

- Subject: [PATCH] Correct pascal parser problem.
The following patch fixes a problem when parsing
expressions that started with fields of this.
If you where in a method that have a filed named owner
that is a pointer,
(gdb) p owner
$1 = (PSYMTABLE) $507a48
(gdb) p owner^
Type TNAMEDINDEXOBJECT has no component named OWNER^.
The problem was that lookup_struct_elt_type
was call with 'OWNER^' instead of only 'OWNER'.
After that patch, I get this:
(gdb) p owner
$3 = (PSYMTABLE) $507a48
(gdb) p owner^
$4 = {NAME = $0, DATASIZE = 0, DATAALIGNMENT = 2, SYMINDEX = $507a78,
DEFINDEX = $507a98, SYMSEARCH = $507ab8, NEXT = $5075f8, DEFOWNER = $507ad8,
ADDRESS_FIXUP = 0, UNITID = 0, SYMTABLELEVEL = 0,
SYMTABLETYPE = RECORDSYMTABLE, _vptr$ = {$4eb2c8, $1}}
which is much better.

* p-exp.y (name_not_typename): Use copy_name to
set current_type variable for fields of THIS.
