Re: [ros-dev] [ros-diffs] [fireball] 23524: Force -fno-sibling-call-optimisation to every module's CFLAGs. This fixes *numerous* bugs (thanks to a bug in GCC itself), even in DBG=1 builds! Just an example, comctl32.dll doesn't crash anymore in LISTVIEW_Callback(). Thanks to Dmitriy Philippov (aka Shedon) for encountering the comctl32 bug and investigating it!
