Comment (by dunfield):
I tried out version (3) of this patch on OS X version 10.9 (which has the
old `as`) and now NTL compiles fine. So it looks good at my end.
One very minor quibble with the OS X-specific comment in the spkg-install
file:
{{{
TODO: If we pass '-q', it suddenly becomes LLVM's 'as', which should work.
}}}
It is true that NTL will compile if you add `-q`, but I wouldn't recommend
doing so just for NTL, only Sage as a whole; I've seen weird segfaults
when I've tried mixing the two assemblers...
