QT compilation with-qtnamespace and static openssl link fail

for 4.8.1 when using -qtnamespace QT and static openssl lib the compilation failed using following configure command line:
configure -qtnamespace QT -opensource -platform win32-msvc2010 -debug-and-release -fast -qt-zlib -qt-sql-sqlite -no-qt3support -qt-libpng -qt-libmng -qt-libtiff -qt-libjpeg -mp -openssl -openssl-linked -webkit -script -scripttools -declarative -qt-style-windowsxp -qt-style-windowsvista -l wsock32 -l advapi32 -l gdi32 -l user32 -l crypt32

the error seems to be when compile ssl support libs the openssl headers chokes, this may because the macro collisions when using QT namespace?
