If you replace the NULL with (void*)0 in GSIMap.h, does that fix it?

Fred suggested to write the macro as
#define GSI_MAP_CLEAR_VAL(node) GSI_MAP_WRITE_VAL(map, &node->value,
(GSIMapVal)(void *)NULL)

If I try
#define GSI_MAP_CLEAR_VAL(node) GSI_MAP_WRITE_VAL(map, &node->value,
(GSIMapVal)(void *)0)

It still compiles. What fix do you consider better ?

I prefer the first one. On systems with a well defined NULL we just have a redundant type cast and on the others we at least express that we want to deal with NULL. For the compiler it should be all the same.
