Please describe the problem:
When compiling applications with -Wshadow enabled, GCC gives the
following warning:

/usr/include/glibmm-2.4/glibmm/helperlist.h:40: warning: declaration of
‘gparent’ shadows a member of 'this'

Steps to reproduce:
1. compile one of the example programs with -Wshadow
for example:
g++ parser.cc -o parser `pkg-config glibmm-2.4 --cflags --libs`


Actual results:
warning of shadowed member is generated:

/usr/include/glibmm-2.4/glibmm/helperlist.h:40: warning: declaration of
‘gparent’ shadows a member of 'this'

Expected results:
compile without warnings

Does this happen every time?
yes

Other information:
fixed by simply changing the name of the variable used in the HelperList constructor.
