// There are many sick systems out there:
//
// check for sizeof(float) and sizeof(double)
// if sizeof(float) != 4 this code must be patched
// if sizeof(double) != 8 this code must be patched
//
// Those are comments I fetched out of glibc source:
// - s390 is big-endian
// - Sparc is big-endian, but v9 supports endian conversion
// on loads/stores and GCC supports such a mode. Be prepared.
// - The MIPS architecture has selectable endianness.
// - x86_64 is little-endian.
// - CRIS is little-endian.
// - m68k is big-endian.
// - Alpha is little-endian.
// - PowerPC can be little or big endian.
// - SH is bi-endian but with a big-endian FPU.
// - hppa1.1 big-endian.
// - ARM is (usually) little-endian but with a big-endian FPU.
