* don't create the nestedvars struct for pure assembler routines, as

    those will never call a nested routine using Pascal-level support
    for accessing local variables (even if the nestedvars stayed empty,
    this caused a stack frame to be allocated because a temp of 0
    bytes is rounded up to 4 bytes)
