Thanks for doing this.  The patch in question is in the
README file.  I copy-and-paste it here for completeness.

------------- begin README -----
cxxabichk will complain about several symbol which are not found. These
symbols are in the library, but have not been exported by the gnu linker-map
in CVS. This patch will expose the needed interface. Note that the actual
symbol version use in this patch is open for discussion. This patch is needed
for both gcc 3.2 & gcc 3.3. There is a similar, but different patch needed
for
gcc 3.4.
