I don't know, on Fedora Core 6 (I think results on Debian/Ubuntu should
be different)

$ cat mao.c
#include <sqltypes.h>

mao mao SQLROWSETSIZE;

$ gcc -DBUILD_REAL_64_BIT_MODE -DSIZEOF_LONG=8 -DSIZEOF_LONG_INT=8 -E
mao.c | grep 'SQLROWSETSIZE\|mao mao'
typedef SQLUINTEGER SQLROWSETSIZE;
mao mao SQLROWSETSIZE;

$ gcc -DSIZEOF_LONG=8 -DSIZEOF_LONG_INT=8 -E mao.c | grep
'SQLROWSETSIZE\|mao mao'
typedef SQLUINTEGER SQLROWSETSIZE;
mao mao SQLROWSETSIZE;
