[vtk-developers] vtk cvs and vfw.dll

[David Gobbi]

Hi Luca,

It sounds like there is a bug in Borland C++, because vfw32.lib is not 
supposed to
link to vfw32.dll.  That might seem counter-intuitive, but that's 
Windows for you.

I found a brief discussion about this at borland.com:
http://info.borland.com/devsupport/bcppbuilder/csreadme.txt
It looks like they fixed the problem in 1997, but maybe it snuck back again.
