There's a bit of confusion about how to disable long double support in an R build.
I see --disable-long-double scattered about, e.g. - R-exts: https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Writing-portable-packages - R-admin: https://cran.r-project.org/doc/manuals/r-release/R-admin.html#Solaris - CRAN noLD check description: https://www.stats.ox.ac.uk/pub/bdr/noLD/README.txt - ?capabilities: https://stat.ethz.ch/R-manual/R-devel/library/base/html/capabilities.html However, it's *missing* from ./config (cd r-source && grep "disable-long-double" configure). Instead there appears to be some code built around enable-long-double: ./configure:1808: --enable-long-double use long double type [yes] ./configure:24723:# Check whether --enable-long-double was given. I see the option apparently introduced here in 2012 & the ambiguity is immediate -- the commit mentions disable-long-double but builds enable-long-double. https://github.com/wch/r-source/commit/fb8e36f8be0aaf47a9c54c9effb219dae34f0e41 Could someone please help to clear the confusion?
