Or in other words, + application programs compiled with initial 0.9.8 headers will + be expected to work with future minor release .DLL without need + to re-compile, even if future minor release features modified API. + - Above mentioned API modifications have everything to do with + elimination of a number of limitations, which are normally + considered inherent to 32-bit platforms. Which in turn is why they + are treated as limitations on 64-bit platform such as Win64:-) + The current list comprises [but not necessarily limited to]: + + - null-terminated strings may not be longer than 2G-1 bytes, + longer strings are treated as zero-length; + - dynamically and *internally* allocated chunks can't be larger + than 2G-1 bytes; + - inability to encrypt/decrypt chunks of data larger than 4GB + [it's possibly to *hash* chunks of arbitrary size through]; + + Neither of these is actually big deal and hardly encountered + in real-life applications. + + Compiling procedure + ------------------- + + You will need Perl. You can run under Cygwin or you can download + ActiveState Perl from http://www.activestate.com/ActivePerl. + + You will need Microsoft Platform SDK, available for download at + http://www.microsoft.com/msdownload/platformsdk/sdkupdate/.
