[Rd] R package with Fortran module on Windows? undefined reference to `__stack_chk_fail'

[Kevin Ushey]

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.

Cheers,
Kevin
