[Oisf-users] Just in-case anybody else runs into this ;-).....

I filed a bug with redhat as it seems that passing -march=native on a
Fedora12/13 x86_64 guest running KVM/Qemu, the Qemu virtual cpu is
detected as a pentium-m(32-bit processor) and causes configure to blow
up on 64-bit libs.  If you do run into this issue you can pass
--disable-gccmarch-native as a configure option as a workaround.  We
pass this option by default as on some older debain/slackware boxes
all gcc binaries are built for an i386 target and thus the gcc compare
and swap macro's needed for our lockless ring-buffers aren't available
even though the gcc version supports it.

Regards,

Will
