Problems compiling Qt3 win32 with mingw

[AgarFu]

Hi, I'm following this instructions http://kde-cygwin.sourceforge.net/qt3-win32/compile-mingw.php
But I'm having lots of problems, The first one. Makefile generated for moc directory seems
to be bad, I solve it editing Makefile, change / into \ and executing mingw32-make again, this dont solve
the problem, when mingw32-make finish I execute qmake and mingw32-make again. Finally moc is ok.

Then, go back into src and mingw32-make again. This time compilation ends with an error while
compiling kernel/qwidget_win.cpp, undefined reference to LWA_ALPHA. I found the definition of
this constant in google.

#ifndef LWA_ALPHA
 #define LWA_ALPHA 0x00000002
#endif

 I put it into kernel/qwidget_win.cpp and mingw32-make again.

The last error is this:
