Thank you for the great job.

I guess checking exact size of a type is less necessary in
common.  Checking trueness of an expression might be enough in
most cases, I guess.

E.g.:

  def check_iftrue(expr, headers = nil, &b)
    checking_for("if #{expr}") do
      try_static_assert(expr, headers, &b)
    end
  end

  check_iftrue("sizeof(long) == sizeof(void*)")

than:

  check_sizeof("void*") == check_sizeof("long")

And these 4 methods accepts a name or a list for headers.

It worked for integral constants only.  Now I guess have_macro
and have_var would do the role instead.  Any idea?
