(1) Are there any compatibility issues when going from VMS 4.5 to 4.6
    (in particular with respect to VAXCRTL)?

(2) The on-line release notes of VAX C V2.3 say:

      o  The printf and scanf functions now perform  formatted  output
         and  input respectively with the addition of three new format
         flags (#, +, space) and the following new format  specifiers:
         i, p, and n.

    Who can tell what the new specifiers are supposed to do?
    I did not find them in the VAX C V2.3 RTL manual, or in online HELP.

(3) The "new" VAXCRTL.EXE shipped with VMS V4.6 has a lot of new
    entry points, but the same image id. ("4.1") as the old VAXCRTL.
    Luckily, all of the new entry points are in a page that happened
    to be zero filled in the old image. So, if you're not yet using
    VMS 4.6, and an absolute says "OPCODE RESERVED TO DEC", read it as
    "IDENT MISMATCH WITH SHAREABLE IMAGE".
