dnl MYSQL_CHECK_ZLIB_WITH_COMPRESS
dnl ------------------------------------------------------------------------
dnl @synopsis MYSQL_CHECK_ZLIB_WITH_COMPRESS
dnl
dnl Provides the following configure options:
dnl --with-zlib-dir   - custom location of compression library.
dnl                     MySQL needs both header file (zlib.h) and the library
dnl                     (libz.a). Given location prefix, the macro expects
dnl                     to find the library headers in $prefix/include,
dnl                     and binaries in $prefix/lib. If DIR is "no", 
dnl                     compression and all dependent functions will be 
dnl                     disabled.
dnl The call checks presense of 'zlib' compression library in default or
dnl given location. If there is no default library, the macro falls
dnl back to use zlib bundled along with MySQL sources. But if configure is
dnl called with custom name/path, and there is no library at given place,
dnl the macro bails out with error.
dnl 
dnl If the library was found, this function #defines HAVE_COMPRESS
dnl and configure variables ZLIB_INCLUDES (i.e. -I/path/to/zlib/include) and
dnl ZLIB_LIBS (i. e. -L/path/to/zlib/lib -lz).
dnl
dnl Exception is Novell Netware, where we assume zlib is always present.
