Symbol-munging is not guaranteed to be stable between different compiler
versions. It appears that the patch relies on this specific munge for "any gcc
major-version >= 3", which is at best fairly fragile. For example, I know C++
code compiled by gcc3.1 is not compatible with that compiled by gcc3.3 on OS X.

I'm not familiar with the back-story here...could someone note what bug# led to
the previous change, and maybe an SVN revision# or something? As a naive
outsider who has often gotten bitten by ABI incompatibility and g++ munge
variability, why can't the symbol that got removed simply be re-added, wrapped
by '#ifndef WIN32'?
