gcc 4.1.1 and qt 4.2 installation problem

[dave]

Hi

When I try to configure & compile the qt 4.2 OS edition I get the following error:

g++ -c -oqlocale.o -O -I. -Igenerators -Igenerators\unix -Igenerators\win32 -Igenerators\mac -I..\src\corelib\arch\generic -I..\include -I ..\include\QtCore -I..\src\tools -I..\mkspecs\win32-g++ -DQT_NO_TEXTCODEC -DQT_NO_UNICODETABLES -DQT_LITE_COMPONENT -DQT_NODLL -DQT_NO_STL -DQT_NO_COMPRESS -DUNICODE -DHAVE_QCONFIG_CPP -DQT_BUILD_QMAKE -DQT_NO_THREAD -DQT_NO_QOBJECT -DQT_NO_GEOM_VARIANT -DQT_NO_DATASTREAM -DQMAKE_OPENSOURCE_EDITION ..\src\corelib\tools\qlocale.cpp

..\src\corelib\tools\qlocale.cpp:5631: error: '_control87' was not declared in this scope
mingw32-make: *** [qlocale.o] Error 1

If it will help I'm running xp sp2 on athlon amd using gcc 4.11
this is what the configure script start with:

$ configure -qt-gif

gcc 4.11 was configured with

Configured with: --prefix=/mingw --host=mingw32 --target=mingw32 --program-prefix= --with-as=/mingw/bin/as.exe --with-ld=/mingw/bin/ld.exe --with-gcc --with-gnu-ld --with-gnu-as --enable-

Any idea what causes this error? Any help would be appreciated!

Thanks
