Why wasn't this included in the specs?

Anyway, since crt* .o object files are no longer present in 3.4,
simply checking which version is used should do it:

$ gcc --version | grep 3.3 && echo true

$ gcc --version | grep 3.4 && echo true
gcc (GCC) 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125)
true

Depending on the result, define *dep_objects or leave it undefined.
