Andrey A. Chernov 96700463ec 1) IEEE Std 1003.1-2008, "errno" section, is explicit that 
"The setting of errno after a successful call to a function is
unspecified unless the description of that function specifies that
errno shall not be modified."

However, free() in IEEE Std 1003.1-2008 does not mention its interaction
with errno, so MAY modify it after successful call
(it depends on particular free() implementation, OS-specific, etc.).

So, save errno across free() calls to make code portable and
POSIX-conformant.

2) Remove unused serrno assignment.
