I successfully rebuilt R-devel_2015-03-09 with the most recent version
of Rtools tonight, building both ICU_531 and this time libcurl (7.39)
as well (and OpenBLAS, of course). The internet bug is still there,
but the rest of make-check all passed with flying colors, as did
building 'microbenchmark' from source (with all the other needed
packages, including Rcpp and Hsiu-Kheurn's change to NM was *not*
used). My non-BLAS test tonight ran faster than last night; maybe 1000
iterations aren't enough or I had something else eating up clock
cycles last night. Either way, outside the internet bug, it's looking
good for Windows 64bit (Win7 at least).

Thanks,

Avi
