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,
