To be a JIT-debugger [1] on Windows, gdb has to be able to signal an
event, which is passed to it by command line. If that is not done, the
process being debugged will not come out of a waiting loop after gdb
attaches to it.
If the event is signaled, Windows will break the loop, and let the
exception fall into gdb's lap (well, stack will be a bit borked, but
that's another issue for another day, and there are ways of working
around it), after gdb user does 'continue'.

The attached patch [2] does exactly that by adding extra
"--event=EVENT" argument, thus AeDebug command line will look like this:
c:\mingw32\bin\gdb.exe --pid=%ld --event=%ld
