Compiling the following C code:

int foo(float bar)
{
    return __builtin_bit_cast(unsigned int, bar);
}

Results in the following errors:

foo.c(3): Error: expression expected, not `unsigned`
foo.c(3): Error: found `int` when expecting `)`
foo.c(3): Error: found `)` when expecting `;` following `return` statement

I'm using macOS 13.0.1, DMD v2.101.1 and Xcode 14.2.
