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
seems OK.

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.
