What is this fix for , why for IAR is a pointer to 32bit , otherwise to 8 bit?

[GustavWi]

#if defined (__ICCARM__)
t->def.stack_pointer = (uint32_t*)malloc(stacksize);
#else
t->def.stack_pointer = (unsigned char*)malloc(stacksize);
 #endif

t->def.stack_pointer is of type uint32_t *. In GCC assigning pointer of a different type generates a warning. IAR's compiler does not allow it and generates an error. I had to correct it so IAR can compile the code.

[0xc0170]

Means , that GCC generators warning and we should fix that

[GustavWi]

Ok I did not want to change any of your code. So should I make a 2nd commit?
Replacing:

#if defined (__ICCARM__)
t->def.stack_pointer = (uint32_t*)malloc(stacksize);
#else
t->def.stack_pointer = (unsigned char*)malloc(stacksize);
#endif

With:

t->def.stack_pointer = (uint32_t*)malloc(stacksize);

Yes, it was changed in the declaration of stack pointer but not in ethernet.
