Compiling Emacs trunk r106057 on Windows 7/64bit. 

For some reason the below error does not seem to happen on `ming32-make
bootstrap'. My own nightly build with `make bootstrap' built fine.

`mingw32-make' yields the following error:

I cannot reproduce this.  It could be a GCC or Binutils dependent,
though.

Did you try removing all the *.o files in oo/i386/, and rebuilding?

I noticed that I was using a gcc 4.4.0 version that came with the Qt 
libraries. IIRC, at some point mingw needed to be patched to work with 
Qt so there might be some modifications in that compiler that are acting up.

I retried with the latest tdmMinGW32 4.6.1 and the error does not occur. 
I have also not seen it with tdmMinGW32 4.5.2, which I have been using 
for months now.

I you don't think that this is worth investigating further, I'll close 
the bug report.

Thanks,
Christoph

I don't mind investigating the problem with Qt's supplied GCC, but
that requires a GCC/Binutils expert.  So unless there's someone here
that wants to bite the bullet, or at least give a hint as to what
could be wrong, I'm inclined to close it as "wont fix".
