  I have reapplied this patch from last year;

https://sourceware.org/ml/gdb-patches/2014-05/msg00480.html

This fix was lost when the change that added the gdb.cp/var-tag.exp 
testcase was reverted and then restored again a few months ago.  In the 
restored version of the testcase, there were 12 FAILs fixed by this 
patch, rather than 9 as previously reported in the original version:

FAIL: gdb.cp/var-tag.exp: before start: c++: ptype E
FAIL: gdb.cp/var-tag.exp: before start: c++: ptype ee
FAIL: gdb.cp/var-tag.exp: before start: c++: ptype EE
FAIL: gdb.cp/var-tag.exp: before start: c++: ptype E2
FAIL: gdb.cp/var-tag.exp: in main: c++: ptype E
FAIL: gdb.cp/var-tag.exp: in main: c++: ptype ee
FAIL: gdb.cp/var-tag.exp: in main: c++: ptype EE
FAIL: gdb.cp/var-tag.exp: in main: c++: ptype E2
FAIL: gdb.cp/var-tag.exp: in C::f: c++: ptype E

FAIL: gdb.cp/var-tag.exp: in C::f: c++: ptype EE
FAIL: gdb.cp/var-tag.exp: in C::f: c++: ptype E2

Yeah, GCC5 is now outputting (into DWARF) the underlying types used to
implement the enum. I had a patch lying around, but I forgot about it.
Thank you for doing this.

Missing '}' ?
