http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46650 --- Comment #1 from Jack Howarth howarth at nitro dot med.uc.edu 2010-11-25 01:41:33 UTC --- The simplest fix for this issue would be to change the behavior of --enable-build-with-cxx such that only stage2 and stage3 are built with the c++ compiler and stage 1 remains built with the c compiler.

That is: #ifdef __cplusplus #include cstring #else /* Existing code including string.h or strings.h. */ #endif I think it's reasonable for system.h to include C++ system headers when building as C++, and in general for it to use the C++ versions of C headers that have standard C++ versions (but hopefully it only needs to do so right now for cstring).
