Problems building with Microsoft Visual Studio 2005 (VC8)

["Mark Rivers" <rivers@cars.uchicago.edu>]

Folks,
 
I've run into 2 problems building EPICS modules with MS Visual Studio 2005 (VC 8).  These problems do not occur when building with Visual Studio .NET 2003 (VC 7.1).
 
1)  In seq 2-0-11 the executable snc.exe crashes when building state programs.  Thanks to Tim Graber, this was tracked down to the following lines:
 
snc_main.c.orig:        setvbuf(stdout, NULL, _IOLBF, 0);
snc_main.c.orig:        setvbuf(stderr, NULL, _IOLBF, 0);
 
The problem lies with the final argument, SIZE.  It appears that the above syntax should be OK, because according to the Mac documentation I found
 
*****
  The setlinebuf() function is exactly equivalent to the call:

           setvbuf(stream, (char *)NULL, _IOLBF, 0);
*****
 
We have found that specifying a size like 1024 seems to work, but what is the correct way to work around this bug in VC8, if indeed that is what it is?
 
2) When building the "stream" module (2-2) I got the following error when linking the example application streamApp:

If I understand this error message, it is complaining that because LIBCMTD has already been included (because it was done with "link /debug" ?) that LIBCMT is producing duplicate symbols.  This did not happen with VC7.1, with the same version of stream.  I cannot even figure out why it is using the /debug flag, and how to avoid the error?
 
Thanks,
