What fpc defines:
http://www.freepascal.org/docs-html/prog/progap7.html#x323-323000G

what qt4.pas uses to conditionally allow certain methods:
     "BINUX"              =   defines based upon fpc defines
    "MSWINDOWS"   =   same as fpc define
    "DARWIN"           =   same as fpc define
    "QTOPIA"            =  you need to define it, fpc cannot sense, it is not 
the same as arm, because then you could not try qtopia on qvfb on i386. 

sample:
{$ifdef BINUX or DARWIN or QTOPIA }
procedure QCoreApplication_watchUnixSignal(signal: Integer; watch: Boolean); 
cdecl; external QtIntf name 'QCoreApp
lication_watchUnixSignal';
{$endif}



Note that the c++/c code of the binding
needs these aswell. 

#if defined BINUX || DARWIN || QTOPIA
void QCoreApplication_watchUnixSignal(int signal, bool watch)
{
	QCoreApplication::watchUnixSignal(signal, watch);
}

#endif


compile qtopia script therefore contains -D QTOPIA:
g++ -D QTOPIA -D 
Q_WS_QWS -I. -I$QT4I -I$QT4I/Qt -I$QT4I/QtGui -I$QT4I/QtCore -Iqlcl 
qtpas.cpp -o libqt4intf.so -shared -fPIC libQtCore.so.4 
libQtGui.so.4  -Xlinker "-soname=libqt4intf.so"
