By the way, shouldn't Sage be a little faster on my Amstrad PC1512?

In fact I just wanted to get rid of the dirty piece of code in sage spkg
install script and hoped that nobody would actually answer on sage-devel
so that the removal gets undetected.
How about changing
# 32bit apple darwin doesn't like our PIC format asm code
case $host in
core2-apple-darwin* | penryn-apple-darwin*)
path="x86/applenopic/core2 x86/applenopic" ;;
prescott-apple-darwin* | pentium4-apple-darwin*)
path="x86/applenopic" ;;
pentium3-apple-darwin* | pentium2-apple-darwin*)
path="x86/applenopic" ;;
i686-apple-darwin* | pentiumpro-apple-darwin*)
path="x86/applenopic" ;;
core-apple-darwin*)
path="x86/applenopic" ;;
*) ;;
esac
to just
# 32bit apple darwin doesn't like our PIC format asm code
case $host in
core2-apple-darwin* | penryn-apple-darwin*)
path="x86/applenopic/core2 x86/applenopic" ;;
*-apple-darwin*)
path="x86/applenopic" ;;
*) ;;
esac
? (As far as I can see, the above snippet is in the x86/x86_64 (and
32-bit OS/ABI) branch, so we don't have to deal with other archs than
these there.)
Otherwise the build will (sooner or later) fail in exactly the same way
on newer CPUs on 32-bit Darwin.
Btw, it would probably be better to use the applenopic/core2 path on any
post-Core2 CPU as well. Then we'd have to invert the logic, such that
the x86/applenopic/core2 path is *not* chosen / added on
i[34567]86-|pentium*-|prescott-|core- (all with 'apple-darwin*'
appended), but on everything else, hoping that the former list is
complete. (We won't have to add CPUs to that list as time goes by, in
contrast to the post-Core2 list.)
For the sake of Sage, it's probably better to patch MPIR 2.6.0's
'configure' (i.e., the *generated* file) rather than 'configure.in'
(autoreconfing afterwards, which usually causes lots of file changes)
until 2.6.1 (with such a fix) is out.
