Sorry for my late arrival, but the change may not be quite correct.

It makes the use of -fno-var-tracking-assignments conditional on gcc4.3+.  However, according to gcc documentation, that flag doesn’t appear until gcc4.5.  (I don’t have access to any of the relevant versions to see if the option is supported without documentation.)
