Actually, this looks like a mismatch between the configuration of the installed kernel and the configuration of the kernel tree used for the compilation of Comedi. It also looks like the kernel's CFLAGS variable was detected incorrectly, since it appears that CFLAGS is missing -O2. You might want to start from a clean kernel source from kernel.org instead of using a vendor kernel. The upcoming version of Comedi will help somewhat with vendor kernels, but it is highly discouraged with 0.7.66. dave...
