A general description is here.
‘configure’ requires the ‘texi2any’ script from ‘texinfo’ 5.1 or later, in place of the ‘makeinfo’ program.
‘configure’ accepts ‘MAKEINFO=texi2any’ as another way to ensure ‘texinfo’ 5.x is used when both 5.x and 4.x are installed.
‘R CMD check’ checks for the undeclared use of GNU extensions in makefiles, and for makefiles with a missing final linefeed.
‘R CMD build’ will correct line endings in all Makefiles, not just those in the ‘src’ directory.
