Tool/software: TI C/C++ Compiler

I am in CCS3.3 with build tools 7.04 for the 2407a DSP. The code I am building was working code. I am trying to bring it under CCS3.3 and build with tools version 7.04 (both newer). 

This code I am building has a ".vectors" section. This is conflicting with the "vectors" section in the RTS (rts.src). I get the link error "cannot allocate vectors in VECTORS". It looks like the linker put my ".vectors" in the *.map file and is also trying to fit "vectors" (from the RTS) into the same section, but it will not fit. I can see this in the *.map file that the two vector version are being put into the VECTORS section. How can I make my ".vectors" replace or override what is in the RTS library

    The linker does not bring in the code from the RTS library module vectors.obj by default.  There must be some reference from your code or build options to one of the symbols defined in that file.  If we can figure out where that reference comes from, we can probably remove it.

    Here is the source file vectors.asm ...

    ********************************************************************************
* vectors.asm  v7.01                                                           *

        .global _c_int0, RESET
;
;  If additional interrupts have C interrupt handlers (in addition to the 
;  RESET vector), add the appropriate branches to the table below as indicated
;  in the comment for each vector.  Vectors that have no interrupt routine
;  should be handled with EINT and RET instructions.
;
        .asect  "vectors",0

RESET   B       _c_int0
 
INT0    EINT               ; B  _c_int1
        RET
 
INT1    EINT               ; B  _c_int2
        RET
 
INT2    EINT               ; B  _c_int3
        RET
 
        .space  (018h-$)*16
 
TINT    EINT               ; B  _c_int4
        RET
 
RINT    EINT               ; B  _c_int5
        RET
 
XINT    EINT               ; B  _c_int6
        RET
 
        .space  (020h-$)*16
        .end

    The symbols defined in vectors.asm are the names written at the very beginning of the line.  While it could be any of them, RESET seems most likely.  

    Please show exactly how the linker is invoked.  Please copy-n-paste the text, and do not use a screen shot.  Please attach the linker command file to your next post.  So the forum will accept it, add the file extension .txt to it.

    Thanks and regards,
