Hello.
According to my understanding of the changes in R-devel, the flag
-fno-optimize-sibling-calls should no longer be forced when compiling
R. Yet, as I compile R, revision 82603, from source on Windows
(Skylake-X server) I see the flag being passed (example below). Is
this different for Windows than for Unix? The changes header seems to
be its own and not under the "Installation on Unix-Alike" header.
Thank you,
Avi
Hi Avi,
yes, thanks for reminding me, I will remove that in the Windows make
files (in about a week or so). There is no need to be more careful on
Windows than Unix regarding this (actually a bit on the contrary, as
most users use the same compiler). Feel free to remove that already in
your builds.
