Details:

First, findutils-4.2.28 bc_init_controlinfo() contains the line
      ctl->posix_arg_size_max - size_of_environment;
... which does nothing at all.

Nevertheless environment size is correctly subtracted in the first
case in bc_use_sensible_arg_max () - so it works correctly on Linux
- but not in the other cases.

The attached patch:
- removes the abovementioned line without an assignment
- modifies bc_use_sensible_arg_max() to subtract env_size in the
  third case.

I have tested the result on i386 Linux: it passes the test suite
and (find -exec echo {} +) with a large environment seems to work.
I don't have any other platform readily available.
