GMP and static memory allocation

[Benedetto]

Hi everyone,

I am developing some benchmarks for a constrained device (Zolertia 
Re-Mote) which use the GMP library. And due to the fact GMP uses 
malloc()'s to allocate memory i came across this problem: 
https://stackoverflow.com/questions/53885652/contiki-enlarge-heap-size-for-zoul?noredirect=1#comment94620097_53885652.

Basically the size of the heap on this device is not sufficient to use 
GMP and, as you can read in the stackoverflow post, the OS i am using 
(contiki) discourages the use of dynamic memory. My question is: Is 
there an easy way i can compile GMP to use static memory instead?

I have read the info section about "Temporary Memory" but from there it 
seems there is no way to do it.

Thank you in advance,

Benedetto Girgenti
