Subject: Multiple definition of `SqlODBC::SqlODBC() 
I found there are two SqlODBC defined in different sources.
$ grep -n "class SqlODBC" src/*
src/history_odbc.cxx:282:class SqlODBC: public SqlBase
src/history_sql.cxx:293:class SqlODBC: public SqlBase
Both of them will be archived into one library libmidas.a if "HAVE_ODBC" defined. Then if you build a shared library, you will
get a link error as the following:
Linking CXX shared library lib/

Why is the class "SqlODBC" duplicated?
