Please modify this MS specific C code to compile under gcc on both 32-bit & 64-bit platforma and produce the same output: 

#include <stdio.h>

#define ALIGN_BITS  ( sizeof(void*) >> 1i64 )
#define BIT_BITS     3i64
#define BYTE_BITS   14i64
#define SLOT_BITS   ( sizeof( void*) * 8 )-( ALIGN_BITS + BIT_BITS + B
+YTE_BITS )
#define BYTES_PER_SLOT  1i64 << BYTE_BITS

int check_new( uintptr_t p ) {
    ptrdiff_t slot = ( p >> (BYTE_BITS + BIT_BITS + ALIGN_BITS) );
    ptrdiff_t byte = ( p >> (ALIGN_BITS + BIT_BITS)) & 0x00003fffi64;
    ptrdiff_t bit  = ( p >> ALIGN_BITS)               & 0x00000007i64;
    ptrdiff_t nop  =   p                              & 0x3i64;

    printf(
        "address: %p slot: %p byte: %4x bit: %4x nop:%x\n",
        p, slot, byte, bit, nop
    );
    return 1;
}

void main( void ) {
    uintptr_t p;

    for( p = 123456i64; p < ( 1Ui64 << 34 ); p += ( 1Ui64 << 29 ) ) {
        check_new( p );
    }
}

Many thanks!

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
