I think the only reason most libstdc++ headers end up including
<cassert> is for the __debug_alloc allocator in bits/stl_alloc.h

Because that allocator uses assert() to check for memory errors,
<alloc> includes <cassert>, and most things include <alloc>.

If the __debug_alloc allocator was moved out to a non-standard header
that users had to include explicitly then I don't _think_ assert() would
be brought in by any libstdc++ header (C headers are a different matter,
and I haven't looked into it much...)
