Hmm, I wrote a trivial programme parsing long ints and get the following

#include <errno.h>

main (int argc, char *argv[]) {
long int a = strtol(argv[1], (char **) 0, 10);
printf("input='%s' ld=%ld (errno %d)\n",argv[1],a,errno);
}

emily:~/Tmp/C++$ a.out 9223372036854775807
input='9223372036854775807' ld=9223372036854775807 (errno 0)
emily:~/Tmp/C++$ a.out 9223372036854775808
input='9223372036854775808' ld=9223372036854775807 (errno 34)
emily:~/Tmp/C++$ a.out 9223372036854775806
input='9223372036854775806' ld=9223372036854775806 (errno 0)
emily:~/Tmp/C++$ a.out -9223372036854775808
input='-9223372036854775808' ld=-9223372036854775808 (errno 0)

so that seems to work correctly. And I compiled with the same compiler
flags with which postgres was compiled. Apparently long is defined as
'long long int' on alpha, and I tried it with that and it works as well.

I'll have to debug this properly, but first I need to get Friday out of
the way ;-)
