I'm still not clear on what the real problem is.
It seems to me that when using GCC, if you #include <unwind.h>, you
will get the GCC version, since it will come from the installed
GCC include directory, which is searched ahead of /usr/include. That
The original e-mail suggested that there was a problem building
libgcc, but I don't see why that would be. Is that the real problem?
If so we need more details.
