Fix for lang/gcc5

auto_ptr in /usr/include header causes c1plusplus to segfault.

Likely obsoleted by ports r426908. Even if not, please, describe build environment in more detail e.g., backed by poudriere logs and if there're local patches. Don't forget to quote errors which are crucial when remuving cruft in future.

Also, if the compiler is buggy it should be patched rather than stacking more hacks into consumers. While GCC 4.2 in base can't be patched retroactively the ports can and *should*.

devel/boost-libs is fragile if consumers are built with different compiler or flags. Adding -std=gnu++11 would require an exp-run. Besides, GCC in base doesn't support C++11

(In reply to Jan Beich (mail not working) from comment #1)
Hi, yes the patch is now obsolete and boost-libs builds successfully with lang/gcc5 now.

You're correct that I should have included a check for "${COMPILER_VERSION} >= 50", sorry about that!
