its automatic storage, installs the floating-point environment
represented by the object pointed to by envp, and then raises the
saved exceptions. The argument envp shall point to an object
set by a call to feholdexcept or fegetenv, or equal the macro
FE_DFL_ENV or an implementation-defined environment macro. */
