Hi All,

Vote: negative


I am afraid I must vote negative, but there is no other reason than this 
technical error.  There is a problem that came up very late with 
vhpi_user.h file.  We declare the abstract type for characters, 
vphiCharT as char and it must be unsigned char to properly represent the 
VHDL character set.  A compiler warning:
   vhpi_def.c: In function `vhpi_is_printable':
   vhpi_def.c:19: warning: comparison is always true due to limited 
range of data type

led to this and we did not deliver this file until quite late. I 
discussed this with Peter Ashenden when I found it and we agreed that we 
should let it through Accellera and fix it in the IEEE.  So I did.  You 
know, at the time, we both thought it would be reviewed in the IEEE 
before any call for vote, but I appreciate how redundant that might now 
seem.  I never expected to first raise this issue in a vote. :(

The VHPI group should just be asked to propose the fix, just to make 
sure it ripples through the API correctly.
