I've fixed the problems that required me to retract version 1.7.18. The new changes are:

o Fixed an infinite loop in the query mechanism resulting from the strstream change in the previous version. There is an overloaded set of str() member functions that weren't a problem when query objects were based on strstream.

o Query mechanism had a bunch of const-incorrectness: there were several function parameters and functions that were const for the convenience of other parts of the code, but within these functions the constness was const_cast away! This was evil and wrong; now there are fewer const promises, and only one is still quietly broken within the code. (It's in the SQLQuery copy ctor implementation; it should be harmless.)

o Visual C++ projects now look for MySQL build files in c:\mysql, since that's the default install location. (Previously, it was c:\program files\mysql.)
