binaries produced by linux->mingw32 gcc 3.0 cross-compiler crash

[Vaclav Slavik <v dot slavik at volny dot cz>]

Hello,

I have problems with getting gcc 3.0 to work as a cross-compiler for 
i386-mingw32 target and hosted on i386-linux. I can compile binutils 
and gcc w/o problems (well, almost), but binaries produced by the 
compiler won't work, they crash immediately after startup.

Here's how I compiled it:

First I installed precompiled binaries of mingw-runtime-1.0-20010604 
and w32api-1.0-20010606.

binutils 2.9.5.0.31:
./configure --prefix=~/mingw32 --target=i386-mingw32
make && make install

gcc 3.0:
I had to apply these patches first to get it compile:

------------------------------------
(configure script of libstdc++ wrongly assumes newlib, if I remove 
this, then it correctly uses generic code, not newlib-specific in a 
couple of places)

Then:
export PATH=~/mingw32/bin:$PATH
../configure --target=i386-mingw32 --prefix=~/mingw32 \
--disable-shared --enable-languages=c++ --disable-threads
make && make install

When I try to run executable compiled with this gcc, Windows pops up 
standard error dialog about illegal operation. It seems the binary is 
not in correct format, since Dependency Walker (from MSVC) says 
"Could not find the section that owns the Import Directory". gdb 
won't launch it, either, it says "Error creating process 
/cygdrive/e/x.exe, (error -1)" -- i.e. no backtrace available. When 
running i386-mingw32-gcc with -v option, it shows that it uses the 
correct linker and assember..

Am I missing something obvious? Any idea what's going on?

Thanks,
Vaclav Slavik
