-// QXmlStream* was originally in the QtXml module
-// since we've moved it to QtCore in Qt 4.4.0, we need to
-// keep binary compatibility
-//
-// The list of supported platforms is in:
-//   http://qt.nokia.com/doc/supported_platforms.html
-//
-// These platforms do not support symbol moving nor duplication
-// (because duplicate symbols cause warnings when linking):
-//   Apple MacOS X (Mach-O executable format)
-//       special case: 64-bit on Mac wasn't supported before 4.5.0
-//   IBM AIX (XCOFF executable format)
-//
-// These platforms do not support symbol moving but allow it to be duplicated:
-//   Microsoft Windows (COFF PE executable format)
-//      special case: Windows CE wasn't supported before 4.4.0
-//
-// These platforms support symbol moving:
-//   HP HP-UX (PA-RISC2.0 shared executables)
-//   HP HP-UXi (ELF executable format)
-//   FreeBSD (ELF executable format)
-//   Linux (ELF executable format)
-//   SGI IRIX (ELF executable format)
-//   Sun Solaris (ELF executable format)
-//
-// Other platforms are supported through community contributions only.
-// We are taking the optimist scenario here to avoid creating more
-// symbols to be supported.
