Just bug fixes this time:
o Fixed the new localtime() alternative selection code
for VS2003 and various uses of STLport.
o No longer inserting a null character into the query stream
on calling one of the preview() functions. This was harmless
in v2.1, which used C strings more extensively, but began
causing problems in v2.2 due to its wider use of C++ strings.
o Fixed a bug in the Connection copy ctor where it didn't
completely initialize the object.
o Minor speed optimizations in the Row() ctor that copies
data from a MYSQL_ROW structure, and in Row::size().
Patch by Korolyov Ilya.
o Optimized Query::preview_char() a bit. Patch by Jonathan
o Reordered directory list used by autconf when locating the
MySQL C API library. The list is now ordered with the
most likely locations for the library first, so we're less
distracted by incorrect libraries. This fixes a specific
build error under RHEL4 with recent versions of MySQL 5.0.
