eb439bf1a7 Add noieee versions for lround(), lroundf(), lrint(), lrintf(), 
llrint() and llrintf().  Code copied from round(), roundf() and
rint() and modified for return values.  Its possible this may not
do the right things in edge cases, but if so its likely to have
the same issues as the existing round(), roundf() and rint().

All this used by vax (only), and should allow xnest to complete
build.

2dcdd0a999 two disgusting hacks: 
-mk/bsd.lib.mk picks up a .S asm file behind our back (did it do so
 always?). s_modf.S is incorrect; I'm undecided whether it makes sense
 to fix it, so add a stupid rule to enforce the .c file to be used.
-on i386, s_tanh.c gets miscompiled. It works with -O0, so add
 COPTS for exactly that file.

d4def06880 -build ldexp/frexp/modf locally again rather than relying on libc 
reaching over, to get things into a sane state,
-do the usual namespace protection game with scalbn(f) because it
 is used internally
(more symbol renamings are necessary)

The weak_alias change for mc68881 is untested.

fddc3457b2 Change the use of formally undocumented features, which have now been

39ba286079 as in exp(), treat +/-Inf and NaN arguments specially, should fix 
eg expf(-Inf) which was Nan previously
(We could avoid touching the i387 on amd64 in these cases, but we'd
need to bypass the ABI abstraction macros, so leave it the old way
for now.)

bc43bac5ca -fix an obvious mistake in fpcw check 
-replace ARG_DOUBLE_ONE_HALF by _MSW/_LSW because this reflects the
 intention and also matches the terms used in C code,
 also make the code where the fpcw overwrites the argument a bit
 self-documenting
 (this abstraction sucks because it forces to write inefficient code)
