Hi Frank, Thanks for your reply. Regarding separate handling of GnuWin32 issues, no problem. I will find a way to contact those folks separately. I just assumed that some of the people who maintain their port of libtiff would read this list as well. Regarding the changes to tif_config.h.vc, there are basically two types of changes in there: 1. Changes and additional settings that were required in order for the build to complete propertly without errors or warnings when using the MSVC compiler. In the end, this was a relatively small number of changes, probably less than half a dozen. 2. Additional settings that resulted from running configure (under MinGW) to generate appropriate settings for an x86 machine running Windows. My justtification for these changes is much weaker without further review. I will attempt to break these groups of changes out separately and provide better justification. Regarding the items in the contrib subdirectory, no building them isn't a necessity, but if you are going to include their source code in your distribution then doesn't it make sense to also include the necessary code to build them? However, I must certainly admit that this is far from a critical issue where my own usage is concerned. Perhaps you are right and this isn't worth the additional maintenance effort. Regarding Bugzilla, will do as soon as I get a chance.
