[QScintilla] Linker error in QScintilla python bindings

[Andre Alexander Bell]

Hello,

I've received a mail by Stefan Bisplinghoff, to copy as a test the 
moc_qsci*.obj files from the QScintilla\Qt4\release directory to the 
Python directory and manually add them to the generated Makefile in 
QScintilla\Python. After that the linker error were gone and I even 
could start Eric with that QScintilla Python binding. This is the same 
as statically linking QScintilla.

Therefore, I thought there must be some error with my compiled version 
of the QScintilla library. I then tried compiling the QScintilla 
example, which works fine. I then tried the Qt4 native examples, which 
work fine. Afterwards I started the same examples from their PyQt 
counterpart, which work fine too. Still I get the linker error in the 
QScintilla python binding.

Now I've tried the same on another machine. Windows XP, MS Visual Studio 
.Net 2003 instead of 2008, again Qt4.4 same error.
