Hsiu-Khuern, using your suggest filter in NM, I was able to build Rcpp in the R_devel compiled with Gcc 4.9.2/win32/seh last night, and I saw around a 10%-15% speedup in Rcpp performance (and R performance in general) from the 3.1.2 version I compiled with Rtool 4.6.3. That may be related to inherent optimizations in 4.9.2 vs 4.6.3, it may be related to seh vs sjlj, or it may be related to passing gnu++11 instead of gnu++0x, I don't know. I do know it was the same code on the same machine, for what it is worth.
