FLOAT    for variables which require at least 32bits
FLOAT8   for variables which require at least 64bits

On some machines, 64bit will be faster than 32bit.  Also, some math
routines require 64bit float, so setting FLOAT=float will result in a
lot of conversions.

   MH: the x86 asm quantization routines in quantize-pvt.c
   are designed to work only with 8-byte doubles or 4-byte
   floats. if you use a different type (e.g. 10-byte extended
   precision long doubles, as supported by ICL), you will need
   to disable the ASM routines (or fix them :)
