ffbd94556b Change isnan() and isinf() to use a union to convert from double to 
struct ieee_double, rather than a pointer cast.  This seems to enable
GCC 2.95.3 to get the instruction dependencies right (the old one fell
foul of ANSI aliasing rules), and it also generates more sensible code in
general.

If this is the correct solution, it should be applied to the other ports.
If it's not, someone should come up with one that _is_ correct.

129f58b424 On the 68010, don't bother with the by-8-longwords loop, instead 
only 16-bit align the region and use loop mode with longwords
to do the bulk of the work.

On the 68020+, fixed an optimization bug where all regions that start
on odd addresses would not be properly longword aligned.

d74323a8be On m68000, all code is compiled softfloat, so functions 
that return floats must do so in integer registers, as the
pre-SVR4 ABI code did.  So in these functions we ignore
__SVR4_ABI__ if __HAVE_68881__ is not also set.

b25c2304f3 I have no idea why this syscall wrapper does some very un-unix-like 
argument prefrobbing, in particular, it computes max(addr, __minbrk)
and uses that. The code is like this even in the ancient libc/i386 tree,
back to the earliest rev 1.2. I did not see it Lite 1, but I'm not totally
sure what the random site I found was serving up.
*
* However, I do know that it should use jb and not jl.
