[Rd] R-devel, bool, and C23

[Dirk Eddelbuettel]

Follow-up and 'case (sort of) closed': Tomas and I dug around some more and
it is due to me setting CC in ~/.R/Makevars (to

  VER=-14
  CCACHE=ccache
  CC=$(CCACHE) gcc$(VER)

which drops the compilation standard flag (needed here for C23) and attached
to CC by configure.

I think that is actually buggy. It should attach it to CFLAGS, no?
