Exactly.
E.g. PGCluster patches configure, not configure.in,
among others. The sugar on the top is PGCluster ruins
the nice portability of PostgreSQL. E.g. plain usage of
fork() without considering EXEC_BACKEND
is not portable across archs.

If the autotools and bison is different,
they may certainly produce different files.
