We compile with VC10 and gcc 4.5 at my work. We've found the boost guidelines to be very helpful in catching cross-platform problems early: https://svn.boost.org/trac/boost/wiki/Guidelines/WarningsGuidelines (see the 'Defining Warnings as Errors' section, particularly 4239 and 4346, which may have helped in this case).
OK, I'll change my warning level to 4 and fix everything I can. Seems like boost::gil generates quite a few warnings, as well. But that's for later.
Yes, there are some warnings at level 4 which are very often triggered by GIL. Common ones are: conditional expression is constant, assignment operator couldn't be generated due to reference member, and more when compiled in 64-bit. <rant>The second is particularly annoying -- if I wanted to be able to copy-assign, I wouldn't have put a reference member in there!</rant> I tend to suppress those particular warnings as a matter of course -- GIL code would not be improved by hacking around these illegitimate warnings. . . Good luck, Nate
