Error while compiling with 2008.

I'm trying to compile library QtWebKit using VS2008 compiler optimization /QRfpe- (Enable floating point emulation: No) for Architecture ARM4. If I remove /QRfpe- I can compile DLL without problems, but if I try to use it I've got a compile error in file animationbase.cpp (888). See attachment. I'm cross-compiling using VS2008 for Windows Embedded CE 6.0.

Thanks for help.

I posted this issue to MSDN forum... they said it's a problem of Qt. Then I opened a bug with Qt... they said I shoud report to WebKit. 
The option /QRfpe- as described here  http://support.microsoft.com/kb/947894 - is not passed correctly by VS2008, so users that need hardware floating point have to add it manually.

AFAICS this is a internal compiler error?
Did you try to fix this problem?
Do you know a workarund for this?

I didn't find a solution and didn't find a workaround. Sorry.

[Patrick R. Gansterer]

Ok, I'll try to reproduce it with VS2005. I don't have a VS2008.

[Patrick R. Gansterer]

Is it possible that this flag is new in VS2008?
I get "cl : Command line warning D9002 : ignoring unknown option '/QRfpe-'" when adding this parameter. Sorry.

The flag means "use hardware floating point", but it's available only if target is ARM.

Please follow http://trac.webkit.org/wiki/QtWebKitBugs when reporing bugs here.

I don't get it, you have "An internal error has occurred in the compiler.", Microsoft refuse to fix their compiler so you report the bug here? What do you expect from us?

NP. As you can read in my first post, the first message about this issue was with MS, that said it's a Qt problem. I'll make some test by my own.
Thanks
