Configured with: ../gcc-4.0-20041226/configure --prefix=/opt/gcc-4.0-20041226-na--enable-shared --enable-languages=c,c++ --enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu --disable-nls --program-suffix=-4.0-20041226-na --disable-checking Thread model: posix gcc version 4.0.0 20041226 (experimental) > g++-4.0-20041226-na nan.cc > ./a.out 0.555556 0.555556 > g++-4.0-20041226-na nan.cc -march=pentium3 > ./a.out 0.555556 0.555556 is this mysterious? because now everything looks o.k. for compilation of gcc-4.0-20041226 i used gcc-4.0-20041212.
