Well, no, that can't be the way.  libgcc is always linked, and any
calls into it need to be far calls (where applicable).  If we want to
supply two different libm.a options, then we should offer that as a
user-selectable option, but still keep it outside of libgcc.a.

I tend to classify these routines as `broken' if they don't yield the
same results as libgcc.a ones.  If we supply replacements for libgcc
functions (because we could get the job quicker done than the generic
code), they need to behave exactly the same.  Even then, I think these
functions should rather be imported into libgcc.a then instead.

So I think that bug should be resolved by using XJMP instead of

Other opinions?
