[Pkg-postgresql-public] Bug#763098: libpq-dev: pg_config_manual.h redefines CACHE_LINE_SIZE

[Sebastian Harl]

Package: libpq-dev
Version: CACHE_LINE_SIZE
Severity: normal

Hi,

pg_config_manual.h redfines CACHE_LINE_SIZE in sys/param.h on kfreebsd:

  /usr/include/postgresql/pg_config_manual.h:219:0: error: "CACHE_LINE_SIZE" redefined [-Werror]
   #define CACHE_LINE_SIZE  128
   ^
  In file included from /usr/include/machine/param.h:8:0,
                   from /usr/include/sys/kglue/sys/param.h:143,
                   from /usr/include/sys/kern/param.h:1,
                   from /usr/include/osreldate.h:1,
                   from /usr/include/x86_64-kfreebsd-gnu/bits/param.h:36,
                   from /usr/include/x86_64-kfreebsd-gnu/sys/param.h:31,
                   from collectd.h:214,
                   from postgresql.c:39:
  /usr/include/machine-amd64/param.h:97:0: note: this is the location of the previous definition
   #define CACHE_LINE_SIZE  (1 << CACHE_LINE_SHIFT)
   ^

This causes build-errors when using -Werror. I assume that this is a
rather unusual use-case, thus didn't mark this RC.

Currently, it causes FTBFSs for collectd on kfreebsd-*, see e.g.
<https://buildd.debian.org/status/fetch.php?pkg=collectd&arch=kfreebsd-amd64&ver=5.4.1-3.1&stamp=1408492216>
I hope, I'll be able to work around it using -Wp,-w there.

Cheers,
Sebastian
