What versions of GDB does WinGDB support?
WinGDB does support GDB 6.x/7.x, although current version of WinGDB is being tested mostly under GDB 6.8/7.x. It’s safe to use this (or newer) version and we strongly suggest it. Most of features work on older versions also. However, older versions of GDB have serious drawbacks e.g. in handling breakpoints with multiple locations. Currently WinGDB utilizes the “pending breakpoints” feature if available, else it will be emulated if possible.
