bug#5754: Bytecomp Arithmetic test failed

[Juri Linkov]

I tried to run some tests in the `test' subdir,
and `bytecomp-testsuite-run' in `test/bytecomp-testsuite.el' fails
on one test: (let ((a (expt 2 -1074)) (b 0.125)) (* a 8 b))
returns 5e-324 when evaluated by interpreter,
but after byte-compilation returns 0.0

In GNU Emacs 24.0.50 (x86_64-pc-linux-gnu) of 2010-03-23
