rsp_zfs and gcc 3.4.x [Dalton]

In Dalton FAQ it is written that "g77-3.4.2 (Fedora Core 3) miscompiles DLAMC3 routine from gp_zlapack.F file leading to apparent hang in rsp_zfs test". I had the same problem (hangs of rsp_zfs) on my CRUX with gcc-3.4.4. Adding of -ffloat-store option helps. Moreover, after adding this option Dalton has been build without and failed tastes on Athlon.
