Lots of embedded processors have 16 bit int and 32 bit long, and 80186 
compatibles are still being produced and sold, although gcc -m16 now has 
limitations.

[The ancient PDP-11 is still supported by gcc 13:

probably because it may still be exemplary CISC ISA in comp arch courses using 
simulators like SimH et al.]
