missing_algorithm_include.diff

Include <algorithm> in concurrent_queue.h, which uses std::equal in the
operator== of both concurrent_queue and concurrent_bounded_queue but relies on
some other header dragging <algorithm> in.

libc++ trunk (as used by CRAN's clang-trunk / clang 23 checks) no longer
provides that transitive include, so building the bundled oneTBB fails with
'no member named equal in namespace std' when compiling
src/tbb/concurrent_bounded_queue.cpp. Sibling containers -- concurrent_vector.h,
concurrent_lru_cache.h -- already include <algorithm> explicitly; this brings
concurrent_queue.h in line.

Not yet fixed upstream as of oneTBB master; drop this once it is.
