Mostly a cosmetic release:
o Fixed the --with-mysql-lib and --with-mysql-include flags'
behavior, and extended their search ability to handle one other
common case. (Fixed by Steve Roberts)
o Fixes to put freestanding functions in namespace mysqlpp. (They
weren't in the namespace, while all the class member functions
were.) This required bumping the ABI version number to 4.
o Renamed set module to myset, to avoid conflicts with Standard C++
Library's set.h when MySQL++ headers were installed into one of
the standard system include directories.
o Renamed all the idempotency guards to make them consistent in
style and unique to MySQL++.
o Reformatted all of lib/*.cc.
As always, it is available at http://tangentsoft.net/mysql++/
