Q_UINT32 undeclared !

[darshan.hardas]

I'm porting the qt3 code to qt4.3.2

I have a variable of type Q_UINT32

static const Q_UINT32 cm_FileIdentificator;

static const Q_UINT32 cm_FileIdentificator;

To copy to clipboard, switch view to plain text mode 

Now in the build system Makefile I have commented QT3_SUPPORT
I get the error

ISO C++ forbids declaration of 'Q_UINT32' with no error

ISO C++ forbids declaration of 'Q_UINT32' with no error

To copy to clipboard, switch view to plain text mode 

Please help me out of this problem
