The gcc patch is almost in... (I hope). While testing it I found one
more testcase that should get the same treatment as gdb.cp/classes.exp
to optionally accept a underlying type in the case of C++.

With the gcc patch you'll get the following 9 failures otherwise:

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: 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 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 EE

With the testsuite tweak all these PASS.

Does this look OK to check in?

Thanks,

Mark

Thanks, Mark.
This is ok.
