]OK, I have followed Jim's suggestion.
]I have uploaded four draft 6 files, one each of FrameMaker and PDF for
]the vpi_user.h and sv_vpi_user.h changes.
]I consider the change to add the vpiObjId less controversial and more
]necessary. Search the AnnexN files for vpiObjId to see the change.
]
]The other change fixes something 'real', for anyone who has an
]application that includes acc_user.h or veriuser.h in any file ahead of
]vpi_user.h, but the existing draft 5 proposal is 
]self-consistent without
]it, and the workaround is to promote vpi_user.h ahead of any of the
]others in the application source code. Search the AnnexL files for SVPI
]to see the change.
]
]I'd appreciate a review and thanks to Jim for already taking the time,
]Abi

]I'm thinking that you could add a revised proposal without deleting the
]existing one, with a Note saying that this new one has not yet been
]approved by the SV-CC.
]Then the SV-CC could consider it and (assuming that we agree to the
]changes) petition the Working Group to allow a substitution on the
]grounds that we found typographical inconsistencies.

]]Subject: RE: [sv-cc] No SV-CC meeting today ] ]hi Charlie, all, ]I was
]hoping for a meeting because I have a couple of issues. Here is ]the
]first one.
]]
]]I have identified a couple of necessary but minor changes to 2226
]](dynamic objects).
]]#1 - vpiObjId doesn't have a #define
]]#2 - placing the new 64-bit vpi_user.h type definitions within the
]]PLI_TYPES include guards has the unfortunate consequence that ]they
]don't ]get defined if there is a preceding acc_user.h or 
]veriuser.h file
]]included in the 'C' file (since it uses the same guard, but doesn't
]]define the 64-bit types).
]]
]]I would like to either
]]
]]a) edit the existing proposal (preferred, but probably too late)
]]b) create a new proposal to fix these things ] ]The first change is
]obviously necessary in order to use the Object ID!
]]If I can't edit the existing proposal to add an editor-define constant
]]then I will propose an actual constant so we can all agree on ]it
]outside ]the 2009 spec. The second change is an actual-usage irritant
]]that people ]using the new vpi_user.h may encounter as I did.
]]
]]The changes are basically:
]]in Draft 6/Annex L (vpi_user.h) change
]]
]]#ifndef PLI_TYPES
]]#define PLI_TYPES
]]typedef int PLI_INT32;
]]typedef unsigned int PLI_UINT32;
]]typedef short PLI_INT16;
]]typedef unsigned short PLI_UINT16;
]]typedef char PLI_BYTE8;
]]typedef unsigned char PLI_UBYTE8;
]]#endif
]]
]]to
]]
]]#ifndef SVPI_TYPES
]]#define SVPI_TYPES
]]typedef int64_t	 		PLI_INT64;
]]typedef uint64_t	 	      PLI_UINT64;

]]typedef short PLI_INT16;
]]typedef unsigned short PLI_UINT16;
]]typedef char PLI_BYTE8;
]]typedef unsigned char PLI_UBYTE8;
]]#endif
]]
]]
]](the 2226 proposal has the new types within the original 
]include guard)
]]and in Draft 6/Annex O (sv_vpi_user.h) change #define 
]vpiPackedArrayNet
]]693 to
