Re: [Xen-devel] redhat 7.3, no always_inline

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

Yes, you need gcc >= 3.2.x. If there's no RPM for RH 7.3 it is easy to
build from source tarball. Xen is happy up to the latest gcc (3.4.1)
but that may not be the case for Linux! A happy middleground is
perhaps 3.3.3.
