#21 Coding Change

[Wave]

This isnt really a bug, but I thought this was the best place for it.

When compiling IBPP into projects that use wxWidgets you get several errors relating to redefinition of SQL_. I changed my copy of IBPP so it uses the defines of IB_SQL_ and it eliminated the issue.

What I'm suggesting is that the project change its defines from SQL_ to IB_SQL_ or something equally as unique.

I modified the following files:
ibase.h
exception.cpp
row.cpp
array.cpp
