If cppcheck is run without the 'platform' argument it will out the following as the first output, which breaks XML parsing:
'cppcheck: Windows 64-bit binaries currently default to the 'win64' platform. Starting with Cppcheck 2.13 they will default to 'native' instead. Please specify '--platform=win64' explicitly if you rely on this.'
As a result checks fail in Eclipse with the error 'Content is not allowed in prolog.'
A way to specify the platform argument needs to be added in order to use cppcheclipse in Eclipse.
