This has nothing to do with the backend. ecpg itself core-dumps after
calling abort() at the end of the switch statement in typename.c, when
processing a .pgc file. As people complained to me about ecpg
core-dumping I tried to find out why and then found that it called the
abort() at the end of this switch ;-)

I have not looked at ecpg in any detail, but I expect that the types in
typename.c are derived from the host variables in some way. If we have
an int8 column in a table, we need to use a 64 bit type, i.e. a 'long
long', and as HAVE_LONG_LONG_INT_64 is not true, no such type is
compiled into the switch. As HAVE_LONG_INT_64 is defined on alpha, my
fix fixes this for alpha, and any other platform where HAVE_LONG_INT_64
is defined but not HAVE_LONG_LONG_INT_64. 

From Tom's mail I gather that it is not an option to define
HAVE_LONG_LONG_INT_64 on alpha, so I think this patch, or something
similar, is necessary.

Apologies for not being clear enough initially.
