Inline::C uses its own Inline_Stack_(Vars|Reset|Done) macros in place of XS's dSP|EXTEND macros. Inline_Stack_Push is used instead of mPUSHi, although you can still use the mXPUSHi form to simplify. See "#The_Inline_Stack_Macros" in Inline::C.

The Inline docs say that you should be able to use the old macros, but I cannot see how to make that work.

Having made the changes mentioned above, this code now works for me: 

#! perl -slw
use strict;
use Inline C => Config => BUILD_NOISY => 1;
use Inline C => <<'END_C',  NAME => 'rand64fast', CLEAN_AFTER_BUILD =>
+ 0;

void rnd( int n ) {
//    dSP;
//    static __int64 y = 2463534242; 
    static int y = 2463534242; // My machine is 32-bit.

//    EXTEND( SP, n );
    Inline_Stack_Vars;
    Inline_Stack_Reset;
    while( --n ) {
        y ^= y << 13;
        y ^= y >> 17;
        y ^= y << 5;
//        mPUSHi( (IV)y );
        Inline_Stack_Push( sv_2mortal( newSViv(y) ) );
        // mXPUSHi(y); // Could have used this instead. Note the added
+ X
    }
//    return;
    Inline_Stack_Done;
}

END_C

print for rnd( 100 );

Caveat: All my XS knowledge predates Inline::C, so any of the above could be flawed in minor ways.
