From Balint: [PATCH 1/2] Revert "Try to fix the "LNK4217: locally defined symbol" warnings. This reverts commit r48158. [PATCH 2/2] Employ small hack in editcap to link with a few objects from libwireshark properly From me: Add the ability to reset symbol exports via ws_symbol_export.h's include guard and do so in capinfos.c and editcap.c. We include ws_symbol_export.h in over 200 files so it didn't seem to make sense to remove its include guard entirely. svn path=/trunk/; revision=48170

Methinks the "not GCC 4 or later" #defines for WS_DLL_PUBLIC and WS_DLL_LOCAL were reversed; that might be what's causing a build error with ui/qt/main_status_bar.cpp. Add some comments for #else's while we're at it, so it's easier to figure out when particular sets of #defines are used. svn path=/trunk/; revision=50329
