- Subject: [PATCH,, PR46650][Revised] Fix --enable-build-with-cxx bootstrap failure
Currently the --enable-build-with-cxx bootstrap is broken due to r167010
which poisoned the strerror macro. The attached patch includes the cstring c++
header when __cplusplus is defined. The previous includes for string.h and
strings.h are left in place for symbols like strcasecmp. Bootstrap and
regression tested on x86_64-apple-darwin10.

Okay for gcc trunk?
