(...) My sources (gcc-3.0) say: #define INT_TYPE_SIZE (TARGET_INT32 ? 32 : 16) A short experiment revealed that sizeof(short)=sizeof(int)=2, sizeof(long)=4. So int is normally 16bit. Only with the switch "-mint32" I get 32 bit ints. This is with a (...) (23 years ago, 12-Jul-02, to lugnet.robotics.rcx.legos)

That is very interesting Jason. It is interesting that mm_free_mem() returns a 16bit value using a 32bit return code. Both int and long are 32bit value on most computers/compilers these days; short would be a 16bit value; and char would be an 8bit (...) (23 years ago, 11-Jul-02, to lugnet.robotics.rcx.legos)

While the declaration for mm_free_mem is int mm_free_mem(void) The fact is that the RCX has only 32K of memory available. 32K in hex is 0x8000... there's never a need for more than 4 digits in hex.
