Hi,
In the BioC 3.6 release of the dada2 package, I've added sections of C code
that are explicitly vectorized using Intel SSE2 intrinsics. I've finally
got the package building on all three platforms, but to get WIndows/MinGW
building, I've had to add the -msse2 to the PKG_CXXFLAGS (etc) which is now
causing the following warning:
* checking compilation flags in Makevars ... WARNING
Non-portable flags in variable 'PKG_CPPFLAGS':
-msse2
Non-portable flags in variable 'PKG_CFLAGS':
-msse2
Non-portable flags in variable 'PKG_CXXFLAGS':
-msse2
Two questions: Should I care about this warning or can I just ignore it?
Use a Makevars.win (same content as Makevars, but windows-specific,
freeing up Makevars to be non-Windows specific) file to specify the flag
only Windows.
Not sure about other packages using SSE / AVX.

And is there an example Bioconductor package using SSE (or AVX) intrinsics
out there somewhere, or some documentation of best practices?
