Hi,
While compiling on clang, I noticed the following warning: pg_backup_archiver.c:1950:32: warning: comparison of constant -1 with expression of type 'ArchiveFormat' (aka 'enum _archiveFormat') is always false [-Wtautological-constant-out-of-range-compare] if ((AH->format = fgetc(fh)) == EOF) ~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~ Something like the patch attached calms down the compiler... This has been introduced recently by commit cfa1b4a of the 9th of February. Regards, -- Michael
