I added the biquad=1 flag to the cdsParameters block of the following models, and did a make (but not a make install yet) to test for successful compilation. All were OK, so I svn committed them. I'll do a make install later, when people are done for the day. h1susauxb123.mdl h1susauxb6.mdl h1susauxh2.mdl h1susauxh34.mdl h1susauxh56.mdl h1susbs.mdl h1susbstst.mdl h1susetmy.mdl h1susitmy.mdl h1susmc1.mdl h1susmc3.mdl h1suspr2.mdl h1suspr3.mdl h1susprm.mdl h1susquadtst.mdl h1sussr2.mdl h1sussr3.mdl h1sussrm.mdl h1sustmsy.mdl The following models already had the flag and will not be touched: h1susim.mdl h1susmc2.mdl h1susomc.mdl
