This is added by a mingw-local patch that has apparently not yet
made it to the GCC CVS. In any case, first locate the GCC "specs"
file in your MinGW cross-compiler installation - this is located
in the folder $XGCC_DIR/lib/gcc-lib/mingw32/3.3, where $XGCC_DIR
is the folder where you installed the cross-compiler. In this file,
change this line:
 %{mthreads:-lmingwthrd} -lmingw32 -lgcc -lmoldname -lmsvcrt
to this:
 %{mthreads:-lmingwthrd} -lmingw32 -lgcc -lmoldname -lmingwex -lmsvcrt
and you should be done.
BTW, this line is generated from the "#define LIBGCC_SPEC" line in
"gcc/config/i386/mingw32.h".
Hope this helps.
Ranjit.
