Hopefully the other Intel folks will have a better solution, but in the mean time, the right solution to me seems to be to drop -march, put all those CFLAGS in configure.ac, try to compile a segment of code with it, and see if it all goes okay. So the actual enabling will only be done if the CFLAGS actually work with whatever architecture has been selected (presumably by CFLAGS being specified in configure command line). I'll post some additional comments if any after going through the patches. Do you prefer them on the list or on github? Cheers, Arun
