you defined UPDATE_PATH_HOST_CANONICALIZE, which as far I as can tell
is used only by prefix.c.  It uses a function called _fixpath (), but
I can find no definition of it.  The only reference to it in the GCC
tree is in the macro.

This would appear to be a bug, or at least dead code.  What am I missing?

Neil.
