R is compiled using the "-fPIC -O3 -fstrict-aliasing -ffast-math -funroll-loops -mpentiumpro -march=pentiumpro -fschedule-insns2" compiler switches. I used ./configure --with-g77 --enable-blas_risc --enable-readline --with-x for configuring.
I can't help noticing that you are configuring for a RISC optimized BLAS library on an Intel x86 processor. I have no idea if this is serious, but it seems a bit odd.
Since this feature was added for PowerPC Linux distributions at my request, I'll comment on this. I would say that it is very unlikely to be of any help, but it probably won't hurt. The configure script will check to see if libblas_risc can be located. If it can't be found, it won't be used. Configure won't even look for it unless you request it with --enable-blas_risc. Furthermore, I don't believe that configure will actually use libblas_risc unless you also --enable-blas. I could be wrong in that regard. Using --enable-blas_risc could implicitly --enable-blas as well. It's been many months since I wrote that configure option. I do know that configure will test if linking -lblas works first. If that fails, it won't even bother with -lblas_risc. Hope this helps,
