bashrc issue in cygwin

I updated my .bashrc with following text to run ns2 and saved it. 

export PATH=$PATH:/home/user/nsallinone-2.34/bin:/home/user/ns-allinone-2.34/tcl8.4.18/unix:/home/user/ns-allinone-2.34/tk8.4.18/unix
export LD_LIBRARY_PATH=/home/user/ns-allinone-2.34/otcl-1.13:/home/user/ns-allinone-2.34/lib
export TCL_LIBRARY=/home/user/nsallinone-2.34/tcl8.4.18/library

Now when i run my Cygwin, each time it displays error as:

-bash: $'\r': command not found

Even now i have removed the above text but it still gives error.

Do i have to recompile ./bashrc, if I have how i will do that?

    It seems that you edited your .bashrc using an application that added CR to the file.

    Running dos2unix would remove the CR:

    dos2unix /path/to/.bashrc
