MySQL Driver Installation fails with nmake: _WinMainCRTStartup

[JohKa]

I've done all advises mentioned on the following page
http://doc.qt.digia.com/4.7/sql-driver.html#qmysql
but the nmake command runs in an error:
LINK : Error LNK2001: Nicht aufgelöstes externes Symbol "_WinMainCRTStartup",
rekease\mysql.exe : fatal error LNK1120: 1 nicht aufgelöste externe Verweise.

I'm using:
VS2010 x32
Qt5.0.2 x32
MySQL Server 5.5 (just ZIP copy) x32
Win7 x64

I hope you habe some hints how to fix this error.

The same, when I use the C++ Connector of MySQL.
