[Ecls-list] FPE under MSVC

[Goffioul Michael]

Hi,

In attachment, you'll find a trial at supporting floating point exceptions
under MSVC. It seems to work OK, but it triggers a problem: it generates
a FE_UNDERFLOW error when trying to print least-positive-double-float:

> (expt most-positive-double-float 2)
#<a FLOATING-POINT-OVERFLOW>
Broken at EXPT.
>> :q
Top level.
> least-positive-double-float
#<a FLOATING-POINT-UNDERFLOW>
Top level.
>> :q
Top level.
> (progn least-positive-double-float nil)
NIL
>

Is it MSVC-specific or can anybody reproduce it under Linux?

Michael.
