Thanks, that was very helpful. The C11 features I use do actually work in C99
mode, so I will stick with that. I just thought it was kind of "cleaner" to
specify C11 mode when using features from that standard.

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:
for some unstated value of 'work' ...
* checking compilation flags
WRE explains for C++11 14 etc standards but I don't know about C
https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Using-C_002b_002b11-code
BTW I believe this question would be more appropriate for R-package-devel.
