The --std setting for GTK has been removed
Fixed #4893 (FP Uninitialized variable on sizeof of itself)
added basic gtk configuration file. it's not complete. It just contains some data that was extracted from the cppcheck checks.
CLI: don't crash if summary in rule file is empty
Add VS2012 projects for my personal use (using /LTCG, /MP, /RELEASE, /MT)
move astyle options to astyle.ini and use it in runastyle and runastyle.bat
astyle.ini: use --lineend=windows since when having autocrlf=true using --lineend=linux messes up the line endings
Add a script to run coverity with VS2012.
Run lupdate.
