This reverts commit 480434f7ee.
netbsd.compat does not provide include files that are provided by libbsd [1], and it
encumbers its transitive dependents with an obligatory include file that setups
BSD-compatible C environment [2].

Subject: Fix function declaration protection for glibc already providing them

On non-glibc based systems we cannot unconditionally use the
|
|
__GLIBC_PREREQ macro as it gets expanded before evaluation. Instead,
|
|
if it is undefined, define it to 0.
|
|
|
|
We should also always declare these functions on non-glibc based
|
|
systems. And on systems with a new enough glibc, which provides these
|
|
functions, we should still provide the declarations if _GNU_SOURCE
|
|
is *not* defined.
