ok, i see, one question, in the build reports at the BioC site the R CMD 
check warns about this kind of problematic post-increment suggesting 
this is the result of using the option -Wunsequenced

i've been trying to install and check my package using that option but i 
cannot find the way to do it.

could you tell me how have you set up the R CMD INSTALL or R CMD CHECK 
command in the building pipeline so that the compiler warns about this 
problem?

is actually -Wunsequenced a specific option of this 'clang' compiler?

thanks!
robert.
