/* When compiling with /Gy and /OPT:ICF identical functions will be folded in together.

The CAIRO_ENSURE_UNIQUE macro ensures that a function is always unique and
|
||
|
|
will never be folded into another one. Something like this might eventually
|
||
|
|
be needed for GCC but it seems fine for now. */
