Backslashes *ARE* line-joining characters for gcc -- without
any options!

I expect, that your backslashes are not immediately followed by
"\n" (not "\r\n"!). Then, they would not be "line joining"!
This very easily happens, if you transfer a Windows source
onto a Unix system.

I do not know, which editor you are using under Linux.
If you use "vim", then you would not see the "\r" preceeding
the "\n" but you would see a "textmode" in the status
line. Use ":set notextmode" and then write the file back.
This would remove the "\r".
You may use the "tr" utility, too, for the "\r" removal,
once you determined that this indeed is the problem.
