Benjamin, Your change for revision 134805,
2008-04-29 Benjamin Kosnik <[EMAIL PROTECTED]> * include/bits/c++config: Remove space between '#' and 'undef' for _GLIBCXX_LONG_DOUBLE_COMPAT. breaks libstdc++ for powerpc*-unknown-linux-gnu on systems where long double is 128 bits, resulting in lots of "undefined reference" errors during linking. The change from "# undef" to "#undef" causes a match in a sed command in libstdc++-v3/include/Makefile, which looks for "^#undef _GLIBCXX_LONG_DOUBLE_COMPAT. Please revert it for now. Janis
