Changed my testcode to int main(). The error stil occurs.
The system is Windows 7, 64 bit, mingw.

Is use the GCC in a company-specific enviroment with some customized
linkersripts.

We first compile the source file with:
i686-elf-gcc.exe -c C:\temp\2\Main.cpp -o c:\temp\2\Main.cpp.o
-D_GLIBCXX_USE_CXX11_ABI=0

and then call the linker:
i686-elf-gcc.exe C:\Temp\2\Main.cpp.o -o C:\Temp\2\a.out
-Wl,-lstdc++,-lsupc++,-lm -lc 
(i have removed a -specs paramter and some target plattform specific
parameters).

I'm sorry for the incomplete command line.

I still hope the *.a-File analysis from my original post can help you.
