Hi all.

When compiling databases/db5 with CFLAGS+= -stdlib=libc++ I got this:

libtool: compile:  c++ -c -I. -I./../src -D_THREAD_SAFE -O2 -pipe 
-march=native -fno-strict-aliasing -stdlib=libc++ ../lang/cxx/cxx_db.cpp

#define _(msg)  msg     /* Replace with localization function. */
                 ^

The problem is actually on libc++ side and has been fixed upstream:
