I couldn't say whether the resultant behaviour is undefined, implemenation defined, or what. And I don't know whether gcc places any surplus baggage in any segment as a result. The fix was just to make the code correct and hence more portable. This also causes problems when compiling with msvc: make[1]: Entering directory `/home/rob/wine-msvc/dlls/msi' CC action.o action.c action.c(236) : error C2133: 'StandardActions' : unknown size It also might affect compilers on other platforms that Wine might be ported to. As Andy says, it's non-standard behaviour and so could break even in future versions of gcc. I think the patch could be changed so that very few, if any, forward declarations would need to be made simply by moving ACTION_HandleStandardAction to after StandardActions is initialised. -- Rob Shearman
