[Bug fortran/36378] New: Support Fortran files with \r line breaks

[burnus at gcc dot gnu dot org]

A college of mine recently struggled compiling some Fortran files and it turned
out that they used (old) Mac line breaks, i.e. \r instead of Unix \n or Windows
\r\n.
(I have not checked how difficult it is to support this.)

Analogously, one could think of supporting \r line breaks in libgfortran, but I
think this will open Pandora's box. (Maybe the same is also true for the Front
end.)

This could be solved by judicious use of a good source code editor.

Also, we could have the scanner insert a '/n' if a '/r' is found and peeking
ahead does not find a '/n', assuming we are not between quotes in a literal
string.

You don't need a good source code editor.

tr '\r' '\n' < infile > outfile

This should be closed with a WONTFIX.
