Yes, that would be a reasonable explanation, of course, but I don't see
anything suspicious in the build log. GMP configures itself as follows:
| ABI="32"
| CC="gcc"
| CFLAGS="-m32 -O2 -fomit-frame-pointer -mtune=athlon -march=athlon"
| CPPFLAGS=""
| MPN_PATH=" x86/k7/mmx x86/k7 x86 generic"
Those flags ought to work fine with an Athlon Duron. In fact, when I
compile the package manually -- outside of Nix --, then it *does*
succeed the regression test. Whatever the problem is, it looks very much
like its related to Nix in one way or another.
Take care,
Peter
