It's interesting to observe that the various architectures have different
semantics for the floating-point exception flags in the presence of traps:
* On some architectures, modifying bits in some control register does not
actually raise a trap. To raise a trap, feraiseexcept() must do an
Oops, after enhancing a unit test, I noticed that on MSVC, the overridden
feraiseexcept function does not work for FE_OVERFLOW, FE_UNDERFLOW, FE_INEXACT.
This patch fixes it. The enhanced unit test will come later.

fenv-exceptions-tracking-c99: Fix feraiseexce
This module adds the functions that deal with tracking which
floating-point exceptions have occurred:
feclearexcept
feraiseexcept
fetestexcept
It not only adds the functions for old platforms, but also provides
workarounds for glibc and Cygwin bugs.
With this done, it is possible to fix a
