	I ran into this problem a couple of days ago.  Release 3 of
VAXC changed some of the .H files.  You will find the following on
page 9 of sys$help:vaxc030.release_notes

         A few of the above files changed to a  degree  that  programs
         that use those files may need to be modified:
                  .
                  .
                  .
          o  PRVDEF.H -- bit mask macros became bit field  members  of
             structs
                  .
                  .
                  .
         As the above list shows, the most common change was that  bit
         mask macros became bit field members of structs.  Previously,
         bit field members of data  structures  were  specified  using
         macros  that  defined  masks  for  accessing  the  bits.  The
         programmer was responsible for using the masks in conjunction
         with logical AND, OR, NOT, and shift operations to manipulate
         the target bits.  The header files have been changed  to  use
         bitfield  members  of  structs  to  accomplish the same task.
         This allows simple assignment statements to be used to set or
         clear bits.  For example:

             #include prvdef

             union prvdef privs;

             set()
             {
                 privs.prv$vcmkrnl = 1;
             }


	I'm not a C programmer, but I think you can probably get away with
using the old prvdef.H that you had with VAXC V2.4.  Any comments.

	By the way where is Mukesh Prasad?  He's the author and I'm
sure can answer this one.

P.S.
	I think the VMS port of GNU Emacs is really well done.  My heartfelt
thanks to those who toiled ...
