Exactly as my second paragraph says. But in the Windows 2000 time frame applications used to install their own copies of msvcrt.dll in the system directories which means one broken application is all it takes to screw that up. But when the operating system vendor no longer supports a platform it is increasingly pointless for a software person to continue support. At some point you have to call it quits. (For example see who still supports Windows 95, MacOS 7 or Redhat Linux 3.) > and is compilable > with any free compiler (mingw for instance) You are mixing multiple things up. There are two different issues: source compatibility and binary compatibility. SQLite does compile with pretty much any C compiler out there (source compatibility). Binary compatibility is a bit more tricky. The compiler links SQLite against system libraries that provide underlying functionality such as file access, memory allocation etc. What happens is compiler and platform specific. In general the resulting SQLite works with that version of the operating system and any version going forward but not older ones. In the case of Microsoft, they have been distributing the C libraries with the compilers not the operating system and been numbering the C library as part of the file name. Additionally various data structures (eg stdio) have changed between library versions and having multiple versions of the C library used in the same process is a recipe for problems. Applications should be putting the C libraries in their own directories and not system locations. msvcrt.dll (with no numbers) is a special case and is in system directories and in theory is for the use of operating system applications only. Because of that pervasiveness MinGW targets it as the C library. In fact they claim to support no other version, although their compiled DLLs do work with other versions in my experience. BTW I believe the distributed SQLite Windows DLL is actually produced by a gcc cross compiler on Linux, which you could label MinGW as well.
