Hum, still seems an issue with a missing -lstdc++. People have recently 
reported similar issues in other contexts (mingw compiling, etc...), and each 
time it apparently worked in 1.9.x, but not in trunk. I'm not sure what might 
have changed in configure that made libstdc++ to be included before, and no 
longer. I have just diff'ed configure.in in trunk against 1.9 branch, and 
nothing related strikes...

Could you diff the output of the generated GDALmake.opt in trunk and 1.9 ? And 
also the same for config.log ?
