Is a parallel build of Maxima (using make -j N), OK?



If one sets something like

MAKE="make -j 20"

to build maxima with 20 threads in paralllel, is this safe? With well written 
Makefiles this is, but unless care was taken to make sure there are no race 
conditions, this can be unwise.

Does anyone know the status of the Maxima makefile?

We are using ECL as an interpreter. I know building ECL in parallel is unsafe, 
so we are not doing that.
