Hi all,

I know this is maybe not the right mailing-list to talk about that,
but I think it's important for any ODBC users:

I have just downloaded unixODBC sources 2.2.14, did a configure/make
and here is what I get in the unixodbc_conf.h header file:

#ifndef HAVE_UNISTD_H
 #define HAVE_UNISTD_H
#endif
#ifndef HAVE_PWD_H
 #define HAVE_PWD_H
#endif
#ifndef HAVE_SYS_TYPES_H
 #define HAVE_SYS_TYPES_H
#endif
#ifndef HAVE_LONG_LONG
 #define HAVE_LONG_LONG
#endif
#ifndef ODBCINT64
 #define ODBCINT64                      <---- ????
#endif
#ifndef UODBCINT64
 #define UODBCINT64                     <---- ????
#endif
#ifndef SIZEOF_LONG_INT
 #define SIZEOF_LONG_INT 4
#endif


Actually, ODBCINT64 and UODBCINT64 are defined, but as "nothing"...

Later, in sqltypes.h, you can see lines like:

#ifdef ODBCINT64
typedef ODBCINT64       SQLBIGINT;
#endif
#ifdef UODBCINT64
typedef UODBCINT64      SQLUBIGINT;
#endif

There are some lines in sqltypes.h to define a default for these
constants, but since unixodbc_conf.h defines them, I would rather
have expected something like this in unixodbc_conf.h:

#ifndef ODBCINT64
 #define ODBCINT64 long long
#endif
#ifndef UODBCINT64
 #define UODBCINT64 unsigned long long
#endif

This can be critical I think... configure script complete without
any error, but later on, when you compile your sources, you get
warning like:

/usr/include/sqltypes.h:400: error: type defaults to 'int' in declaration of 
'SQLBIGINT'
/usr/include/sqltypes.h:403: error: type defaults to 'int' in declaration of 
'SQLUBIGINT'

Did I miss something here?

Cheers,
Seb
