Looks like _float_long_union in undefined.

There are allot more than this that I modified when the _flot_long_union was
added.

I agree and I do not see any reason for the changes to have broken building
under 2.95.3.

Either I missed something when I did the patch or the only other thing I can
think of is that the ieee.h does not typedef _float_long_union for some
reason.

In include\libc\ieee.h is the following typedef defined?
typedef union
{
  float f;
  long  l;
} _float_long_union;

If the typedef is included in ieee.h if you change the ieee.h to always
define it then does it work? If so then looks like one of the #ifndef's are
a problem.
