31 * Each unique machine architecture needs an entry in this file
32 * So far the differences boil down to: endianness, 32 vs 64 bit pointers,
33 * and on 32bit ones, whether double is aligned to one word or two words.
34 * Those result in the 6 formats listed below.
36 * If any of the assertion errors in fccache.c fail, you need to add a new
37 * architecture. Contact the fontconfig mailing list in that case.
