[SOLVED] [MingW][Qt][Windows XP] warning: cannot find entry symbol nable-stdcall-fixup;

This mingw contains gcc 4.6.3, with name - i686-w64-mingw32.

Qt SDK 2010

On Windows, a Qt's.pro file w.r.t a hello world program:

Code:

QT          += core gui
TEMPLATE    = app
TARGET      = ef

SOURCES     = ef.cpp
DEPENDPATH  += .

INCLUDEPATH += . 
INCLUDEPATH += c:/R-2.15.1/include
INCLUDEPATH += c:/R-2.15.1/library/Rcpp/include
INCLUDEPATH += c:/R-2.15.1/library/RInside/include

LIBS        += -L c:/R-2.15.1/bin/i386 -lR
LIBS        += -L c:/R-2.15.1/library/Rcpp/libs/i386 -lRcpp
LIBS        += -L c:/R-2.15.1/library/RInside/libs/i386 -lRInside

What needs to be added in the pro file to solve this?

EDIT

I had installed this mingw by downloading it from here: http://code.google.com/p/mingw-builds/ and copying all its files in the mingw folder inside Qt.

This is solved.

People from stackoverflow told me that this is a bug in the qmake.conf on Windows.
I had to edit the qmake.conf found in mkspecs/win32-g++ folder in Qt.

qmake.conf
