Hi Jim,

thanks for you answer.
My copy of the file has the same line 427:

    420 %If (Qt_3_0_0 -)
    421                 MaxUser,
    422 %End
    423         };
    424 
    425         QEvent(Type);
    426         QEvent(QEvent&);
    427         virtual ~QEvent();
    428 
    429         Type type() const;
    430 %If (Qt_3_0_0 -)
    431         bool spontaneous() const;
    432 %End

I believe this can't be a CPU overheating problem because I've retried many 
times and it always stops at the same line with the same errors.  A CPU 
overheating wouldn't be reproductable.

I'm using pre-packaged binaries:

[root at pioppo root]# rpm -qa|grep PyQt
PyQt-docs-3.4-1mdk
PyQt-3.8-1mdk
PyQt-eric-3.4-1mdk
PyQt-devel-3.8-1mdk
[root at pioppo root]# rpm -qa|grep sip 
libsip9-3.4-1mdk
libsip10-devel-3.8-3mdk
libsip9-devel-3.4-1mdk
libsip10-3.8-3mdk

both removing "virtual" or commenting the line out stops compilation at line 
1129:

   1125 %If (Qt_2_1_0 -)
   1126         QCustomEvent(int);
   1127 %End
   1128         ~QCustomEvent();
   1129 %VirtualCode
   1130                 // We need to garbage collect any current data.
   1131 
   1132                 PyObject *old = reinterpret_cast<PyObject *>(data());
   1133 
   1134                 SIP_BLOCK_THREADS
   1135                 Py_XDECREF(old);
   1136                 SIP_UNBLOCK_THREADS
   1137 %End

I'm on Mandrake 9.2
When I've more time I'll try rebuilding everything from source, anyway it 
would be nice to understand exactly where the problem is, so that I can send 
feedback to Mandrake people.

Thank you again
