Hi,

what is the correct way to specify a C standard in a package's Makevars file?

Building a package with e.g. PKG_CFLAGS = -std=gnu11 does work but R CMD check issues a warning:

* checking compilation flags in Makevars ... WARNING
Non-portable flags in variable 'PKG_CFLAGS':
  -std=gnu11

(Same for -std=c11.)

Thanks! Regards,
Andreas Kersting
