Note that some language front 7 ends may not honor these options.
-fmessage-length=n
Try to 6 format error messages so that they fit on 5 lines of about n characters. The default 4 is 72 characters for g++ and 0 for the rest 3 of the front ends supported by GCC. If n 2 is zero, then no line-wrapping is done; each 1 error message appears on a single line.

man page for gcc says
-fmessage-length=n
Try to format error messages so that they fit on lines of about n characters. The default is 72 characters for g++ and 0 for the rest of the front ends supported by GCC. If n is
zero, then no line-wrapping will be done; each error message will appear on a single line.
Just a formatting option 1 for error messages.
