ecpg bug and patch

Hi,

I've been doing some tests with writing int8 to the database using
ecpg. This does not work if the long long variable is in a structure, as
it is not recognised as a simple type.

The patch is attached, but is not very satisfactory. Moving the
definition of

ECPGt_long_long, ECPGt_unsigned_long_long

up to before ECPGt_varchar causes the resulting application to crash, as
it finds an ECPGt_union, where it should haven found an ECPGt_EOIT (I
think), and I could not figure out where the static offset comes from.

Another problem with ecpg is that it dies on the alpha for long long
variables unless

#define HAVE_LONG_LONG_INT_64

is set in config.h. It is not set by default.

Without fixing these int8 values cannot be written to the database.

Regards,

Adriaan
