dtoa.c fix from upstream that fixes incorrectly rounded results for certain subnormals that are also halfway cases.

this fixes the first bug described in issue #7743.

Increased the overflow value on test_dealloc to make sure that it is big enough even for wide builds.

This should fix the failure introduced in r77680. The error message is now different and it caused the test to fail. The failing test is not present in 2.5 so it is failing only on 2.6 and newer versions.

4. Remove unused dsign field from BCinfo struct.

This patch should fix most of issue 4834, although I haven't gotten enough

- Issue #7714: Use ``gcc -dumpversion`` to detect the version of GCC on
  MacOSX.

- Make configure look for util.h as well as libutil.h. The former
  is the header file that on OSX contains the defition of openpty.
