OK, I see. Problem is that without the fix ecpg aborts when writing to a
table with an int8 column using valid code.

long int
long long
long long int

all exist on alpha and are all 64 bits, but HAVE_LONG_LONG_INT_64 is not
defined, so ecpg cannot handle ECPGt_long_long types. It is not clear to
me what the best thing is to fix here -- possibly configure needs to set
HAVE_LONG_LONG_INT_64 (which solves the problem on alpha as well), but I
do not know what the consequences of that are.
