Hmm, I'm not seeing these warnings (Windows, gcc 4.4.1, MingW) while compiling with -O3. What other command line options do I need to specify?
"g++" -ftemplate-depth-128 -O3 -finline-functions -Wno-inline - Wall -pthread -DBOOST_ALL_NO_LIB=1 -DNDEBUG -I"." -c -o "/home/john/bin/boost/bin.v2/libs/wave/build/gcc-4.4.1/release/link- static/threading-multi/instantiate_cpp_exprgrammar.o" "libs/wave/src/instantiate_cpp_exprgrammar.cpp"
With gcc-4.4.1.
I see so many pages of warnings from this that I gave up counting :-(
Ok, got it. I started to address those but there are still a couple of the strict aliasing warnings to fix. I'll work on that asap, even if I'm not sure how to address the warnings yet. I just was not aware these warnings get generated... Regards Hartmut ------------------- Meet me at BoostCon http://boostcon.com
