Comment(by leif):
With GCC versions prior to 4.6, you might have to specify e.g. `-fno-
fused-madd` instead on some platforms, so you could also check whether
that's supported and use it in case it is.
[Although it's not immediately clear to me whether that's desirable at
all; with (fused) multiply-accumulate, the results are ''more'' accurate
than without. They'll of course frequently differ slightly from what you
get ''with'' strict IEEE 754 compliance.]
[[BR]]
`spkg-install` should use `$MAKE` instead of `make`.
`$SAGE_LOCAL` should be quoted in the generated script.
There are a few typos in the comments, e.g. ''"default mode of
operat'''ion'''"'' and ''"prec'''is'''ion"'' (instead of ''"precion"'').
