unixODBC 2.2.14 defines SQLLEN and SQLULEN using the compiler typedef
declaration instead of preprocessor #define macro definition.  This breaks
the preprocessor checks in this include file.cpp, causing the source to fall
back to older types instead, leading to compile time errors like this:

db.cpp:1636: error: cannot convert ‘SQLINTEGER*’ to ‘SQLLEN*’ for argument ‘6’ to
‘SQLRETURN SQLGetData(void*, SQLUSMALLINT, SQLSMALLINT, void*, SQLLEN, SQLLEN*)’
...
dbtable.cpp:592: error: cannot convert ‘SQLUINTEGER*’ to ‘SQLULEN*’ for argument ‘4’ to
‘SQLRETURN SQLExtendedFetch(void*, SQLUSMALLINT, SQLLEN, SQLULEN*, SQLUSMALLINT*)’
...

This change hard-wires the new names, breaking compatibility with older
unixODBC versions (don't know what version number ranges) in favour of
support for newer releases like 2.2.14.
