[R-pkg-devel] CRAN check FAIL due to pragmas in headers and code

Hi all,

Three days ago, Patrick Perry posted the following on R-devel:

A recent change to r-devel causes an R CMD check warning when a C file
includes a "#pragma GCC diagnostic ignored" pragma:
https://github.com/wch/r-source/commit/b76c8fd355a0f5b23d42aaf44a879cac0fc31fa4
. This causes the CRAN checks for the "corpus" package to emit a warning:
https://www.r-project.org/nosvn/R.check/r-devel-linux-x86_64-fedora-clang/corpus-00check.html

I didn't pay much attention, but today I received a couple of emails
warning about my package failing on r-devel-linux-x86_64-debian (gcc
and clang) with the following message:

Check: pragmas in C/C++ headers and code
Result: FAIL

My package has no pragmas, but Rcpp, on which it depends, does. So
basically Rcpp and all packages depending on Rcpp are failing on that
flavors. Is this a new requirement for new submissions? Or should I
ignore these FAILs?

Regards,
I?aki
