rgl has a lot of C++ code which is now getting errors in the clang17
tests on CRAN:
https://www.stats.ox.ac.uk/pub/bdr/clang17/rgl.log
I haven't looked at the whole list yet, but many of the errors arise
because R's include/Rinternals.h defines a length() macro, and that
conflicts with a definition in clang's library. For example,
/lib64/glib-2.0/include -I/usr/include/sysprof-4 -pthread -Iext
-Iext/glad/include -isystem /usr/local/clang-trunk/include
-I/usr/local/clang/include -fpic -O3 -Wall -pedantic -frtti
-Wp,-D_FORTIFY_SOURCE=3 -c PlaneSet.cpp -o PlaneSet.o

For those R users who know C++ better than me, is there a standard way
to avoid this? I can think of a couple that should work (e.g. defining
R_NO_REMAP globally, or rearranging the order of includes). I'd like to
use the standard one if there is such a thing.
