INN commit: trunk (configure.ac include/clibrary.h)

[INN Commit]

  Author: iulius
Revision: 9291

use new AC_CHECK_TYPE autoconf syntax

Autoconf versions prior to 2.13 provide a now deprecated version
of the AC_CHECK_TYPE macro.  It was doing more than a CHECK, and
was also defining missing types with #define instead of typedef.

Swith to the preferred syntax with AC_CHECK_TYPES and typedef.
