You should be able to set PKG_FCFLAGS="-fno-stack-protector" when compiling to ensure that the stack protector is not used.
(Trying that out on a Windows VM, with a simple `R CMD build` + `R CMD INSTALL`, compilation of your package succeeded but linking failed saying the DLL 'Fpi' was not found; I imagine that's a separate issue.) As an aside, be sure to check out what R-exts has to say on the topic of Fortran code in R packages (especially F90 and above): https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Using-F95-code.
