[Scons-users] linker command under windows not working (too long)

[Bill Deegan]

Won't TEMPFILE work for this?

A callable class.  You can set an Environment variable to this,
    then call it with a string argument, then it will perform temporary
    file substitution on it.  This is used to circumvent the long command
    line limitation.

    Example usage:
    env["TEMPFILE"] = TempFileMunge
    env["LINKCOM"] = "${TEMPFILE('$LINK $TARGET $SOURCES')}"

    By default, the name of the temporary file used begins with a
    prefix of '@'.  This may be configred for other tool chains by
    setting '$TEMPFILEPREFIX'.

    env["TEMPFILEPREFIX"] = '-@'        # diab compiler
    env["TEMPFILEPREFIX"] = '-via'      # arm tool chain
