Issue with NULL pointers on Harvard Architecture platform

Question

Interesting issue we came across here this week.

We are working in C on a Harvard Architecture embedded platform, which has 16-bit data addresses and 32-bit code add

Answer 1

Edit the implemention's system headers to replace all occurrances of

#define NULL ((void *)0)

with

#define NULL 0

Then file a bug report with the vendor. You should not have to modify your (perfectly correct, albeit ugly style) code because of a bug in the vendor's compiler.
