2c764d53fa Make it compile with WARNS=1. (I'm not sure where the prototype really 
should be, but it does now compile.)

fb4d5f58af Fix extra 'S' character typo that resulted in the condition codes being 
incorrectly internally on certain divides.
Handle the case where the internal result appears negative. This condition
can occur when dividing MIN_INT by certain values.
Raise an exception on divide by zero.

is
e6cb27b508 ieee.h and ldexp.c taken from the powerpc port, for the benefit of 
68040 and 68060 owners.
With ``make M68040=1'' or ``make M68060=1'', we build a libc where the ldexp()
doesn't use excessive amounts of system cpu time.
Without any of those defines, the normal assembler version using FSCALE is
included, for the benefit of M68020 and M68030 users, or M68040/M68060 users
where the ldexp performance is no bottleneck.
[Its not yet worked out how to include both library versions in a binary
distribution, but you can build your own from source now if you need it.]
For details, look at PR 3105.

68a9b35134 Do a .cpload if compiling with PIC. 
Examining  the .so output from binutils 2.8 and 2.8.1 shows the
	li.d	$f2, 4503599627370496e0
is (incorrectly?) emitted as GP-relative loads when PIC is in effect.
