I'm using TDM64 GCC 4.5.1 with lto enabled, and it works for eg building Qt without error. I have also built and installed libelf for TDM64 GCC (it's installed in the MSYS /mingw/x86_64-w64-mingw32 directory, with /mingw a symlink to the TDM64 root directory. I am now trying with these options: ../../src/gcc/configure --prefix=/home/ruben/mingw64/build/mingw64 > --with-sysroot=/home/ruben/mingw64/build/mingw64 --target=x86_64-w64-mingw32 > --host=x86_64-w64-mingw32 --build=x86_64-w64-mingw32 > --enable-languages=c,c++,lto --enable-stage1-languages=c,c++,lto > --enable-fully-dynamic-string --disable-multilib --enable-lib64 > --disable-lib32 --enable-lto --enable-libgomp CFLAGS="-mtune=core2 -flto" > LFLAGS="-flto -fwhopr=3" BOOT_CFLAGS="-mtune=core2" BOOT_LFLAGS="-whopr=3" > In the hope that BOOT_LFLAGS will overwrite the regular LFLAGS for the bootstrapping compiler. Am I correct in thinking that configure <options> && make (&&make install) is all I need? Could I perhaos have a look at your build script/commands (if it's not just the one from svn...). Thanks Ruben
