What are the particulars; i.e., is setting CC=icc, and having icc specific libraries in the environment variables icc looks for by default sufficient, or do I need to pass these along as options to configure as well? I can put icc specific flags in CFLAGS, CXXFLAGS, and indicate the libraries in LDFLAGS, according to configure --help. But I need to add the icc specific options `-parallel -xT', and suppress any -mcpu, -mtune or -march options that configure might otherwise deduce from MACHTYPE=powerpc-apple-darwin8.0 and HOSTTYPE=powerpc, which are set by the OS, and which cause gcc to inevitably select for the lowest common denominator; e.g. i386. I'm not sure why Apple declares the HOSTTYPE to be powerpc, when it is in fact, an Intel Mac. Despite this, configure always figures it out, and chooses the architecture as i386, but it never does better; i.e., recognizing that the machine has the full compliment of MMX and SSE1 - SSE3 instruction sets. In icc, all I need do is select -O2 -xT -parallel, and that seems to give the best results. However, if I set CFLAGS='-O2 -xT -parallel', I'm worried that I'm going to override important Scheme options, like -fomit-frame-pointer and such. Will configure add necessary additional arguments in addition to CFLAGS? Also, I see how to disable or enable a features, in configure --help, but I'm not sure how I keep it from using incompatible CPU options, unless it only uses CFLAGS, and then I'm back in the same boat, trying to figure out if I need to add other flags, like -fomit-frame-pointer. Maybe I'm making too much of this, but obviously I'm a bit confused. Clarification would be helpful.
