Re: [R-pkg-devel] How to R CMD build / check using LTO

Hi Paul, I think that changing the Fortran logicals to integers is the easiest way to fix this up. In the old days (1990's and maybe later), there were Fortran compilers that did not map .TRUE. to 1 and .FALSE. to 0, but I suspect that R's .Fortran does not cater to them. I avoid Fortran logical
