This is the problem!

GetAttr ((unsigned long)IA_Width, (APTR)win_resize_image, (unsigned long*)&win_resize_gadget_width);

And casting to

unsigned long*

doesn't help much, when GetAttr() needs an

ULONG*

.

I found out that the exec/types.h header from NDK 3.2 uses C99 stdint.h to define the AmigaOS types like ULONG. In the past it was simply defined as unsigned long. Now ULONG is defined as:

typedef uint32_t        ULONG;          /* unsigned 32-bit quantity */

While vbcc defines uint32_t in stdint.h as:

typedef unsigned int uint32_t;

This explains the warning, because different types (for the compiler) are referenced. The fix is simple. Just use ULONG when you need ULONG.
