[Qt-interest] no more qt from .net applications vice versa?

[master.of.brainless.things at gmx.net]

hello,

i recently noticed that qt for windows is now compiled with _fastcall mechanisms, 
which are incompatible to the _stdcall thing, afaik.

so, as a user of the commercial qt version, now compiled with _fastcall things,
and support option for this qt version,
i'm not anymore able to call qt methods from .net code?

more directly;
if i must use .net environment, e.g. to support .net plugin dlls in my software,
i compile in /clr support.
but in .net _fastcall is now dismissed, again: as far as i know.
this effectly makes it impossible for me to use my qt anymore, right? at least, with a stable behaviour...

on the otherside, one has told me just to recompile whole qt without _fastcall option.
ok.
but wouldn't than my support option/garanty for my qt-version get pointless?

i'd appreciate some ideas,
especially from people who are in same situation!
