It was also suggested that the R-Project doesn’t really care about building with “non-standard” compilers, but I can’t find any evidence of that on the website (indeed, there’s some mention of successful past builds, and the build itself is successful).

Thanks, Bjørn; -ipo no longer breaks compilation (I didn’t specify it, but I see that it was getting added automatically). I was really hoping that "-fp-model precise” (which also implies -prec-div which would seem to affect the other option mentioned) would have an impact on “make check” here, but apparently not. Also -wd188 is no longer required to hide warnings; this doesn’t seem to be happening anymore (but remember it myself from earlier on).

I guess it might make sense to check with Intel; we have support. I wish I could remember if this ever worked right, but I don’t think I thought/knew to run "make check" on our older builds.
