I'm afraid I didn't quite follow the thread, but it looked as if the original discussion about __GXX_WEAK__ being inconsistently defined was not correct, and the fix was to patch the gccxml-0.9/GCC/3.4/bits/gthr-default.h file.   

Yes, this was the fix:

> But there isn't a gthr-default.h supplied for 3.2.3.  I tried naively copying /usr/include/c++/3.2.3/x86_64-redhat-linux/bits/gthr-default.h into the gccxml/GCC/3.2 tree and applying the same patch, but unsurprisingly it didn't work (error: stray '##' in program).

The same fix should work.  Please post the code near the fix.

It should look something like

  # define __gthrw(name) \
    extern __typeof(name) __gthrw_ ## name

after applying the fix.
