I had exactly the same problem you described and tracked it down to
the same reasons. However your patch will omit a lot of useful symbols
I hacked gcc to circumvent the linker problem and now I dont have to hack gdb
and still get all symbols. I'll post the patches (and some other COFF related
patches) to gcc.bug as they belong there. If you are unable to get
them from gcc.bug, please mail me.
