[GCC-XML] weakref must have static linkage (gcc3.2.3)

[james at goldwater.org.uk]

Trying to run gccxml-0.9.0 against a header file that just has 

#include <set>

gives an error about weakrefs and static linkage (see the end of this email).

I've compiled gccxml (I checked it out yesterday from the cvs with the cvs command 'co gccxml', so that's presumably the stable branch?) on the same RHEL3 machine, gcc3.2.3:

$ gcc --version
gcc (GCC) 3.2.3 20030502 (Red Hat Linux 3.2.3-59)

$ ./gccxml --version
GCC-XML version 0.9.0

$ ./gccxml_cc1plus --version
GNU C++ version 4.2.1 (gccxml.org) (x86_64-unknown-1-gnu)
        compiled by GNU C version 3.2.3 20030502 (Red Hat Linux 3.2.3-59).
GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096

This looks very similar to a problem reported at http://www.cmake.org/pipermail/gccxml/2008-August/001171.html, but that was against 3.4.6.  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.   

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).

Can anyone help me?  

James.
