I found the following warning with Fedora 14 / gcc 4.5.1.
----
pg_backup_archiver.c: In function ‘_discoverArchiveFormat’:
pg_backup_archiver.c:1736:11: warning: ‘fh’ may be used uninitialized
in this function
----
To suppress it, I'm thinking to add noreturn to die_horribly().
Any objections? Another solution might be adding a dummy assignment
after calls of die_horribly().
