0001 // This file moves some of the autoconf magic to compile-time when building on
0002 // macOS. This is needed for building 4-way universal binaries and for 64-bit
0003 // universal binaries because the values redefined below aren't configure-time
0004 // constant but only compile-time constant in these scenarios.
