• Fix linker problem by removing libtool dependency. The combination of USE_AUTOTOOLS, USE_GCC and C++ is broken because /usr/local/bin/libtool has hardcoded the linker it was built with. So on FreeBSD 10 it tries to link gcc compiled C++ code with clang which does not work.
• Remove USE_GCC and fix build with clang with two new patches. [1]
• Fix build with libc++ by removing -lstdc++ from linker flags. The compiler automatically adds the right runtime library.
• Add LICENSE.
• Convert gnomehack to pathfix.
• Remove references to PTHREAD_LIBS and PTHREAD_CFLAGS.
• Support staging.
• Remove an old patch that's no longer needed.
