file-spec

    Specifies the character string you want the linker to use as the
    name of the symbol table file. If you do not include a file type
    in the character string, the linker appends the .STB file type to
    the file name.

    If you specify the /SYMBOL_TABLE qualifier without the file
    specification, the linker creates a symbol table file with the
    file name of the first input file and the default file type .STB.
    If you append the /SYMBOL_TABLE qualifier to one of the input
    file specifications, the linker creates a symbol table file with
    the file name of the file to which the qualifier is appended,
    with the default file type .STB.
