Hi Thorsten, I see that gcc-2.95.x is not one of the supported platforms for range, and I assume that there is a good reason for this. However, I have a couple small changes to iterator_range which will make it work well enough on gcc-2.95 for the purposes of the iostreams library, and I'd like permission to commit. I also added some fixes for Intel. Here are the tests I've conducted: VC7.1: passes all tests but mfc Intel 8.0 (windows): passes all tests but mfc Borland 5.6.4: passes all tests but mfc and array (failure in Boost.Test) GCC 3.4.1: passes all tests but mfc GCC 3.2 (MinGW): passes all tests but mfc VC7.0: passes no tests, but same was true prior to the changes, on my installation (although the regression reports show three tests passing) Also, I've updated mfc/cstring and carray to use the new metafunction names, and made some fixes so that they compile on windows, but have not tried linking them.
