2006-04-04 Julio M. Merino Vidal <jmmv@NetBSD.org> * libgtop-sysdeps.m4: * sysdeps/freebsd/msg_limits.c: Use configure checks to detect whether we need to define either KERNEL or _KERNEL to get the definition of 'struct msginfo' in a BSD system. This replaces the previous checks in the code that relied on __FreeBSD__ and similar macros. Before this change, the explicit definition of _KERNEL in the msg_limits.c file broke the build in NetBSD because it made the system headers pull in stuff unavailable to userland. Fixes bug #337207.

dnl This file is intended for use both internally in libgtop and in every program
|
|
dnl that wants to use it.
|
|
dnl
|
|
dnl It defines the following variables:
|
|
dnl
|
|
dnl * 'libgtop_sysdeps_dir' - sysdeps dir for libgtop.
|
|
dnl * 'libgtop_use_machine_h' - some of system dependend parts of libgtop provide
|
|
dnl their own header file. In this case we need to
|
|
dnl define 'HAVE_GLIBTOP_MACHINE_H'.
|
|
dnl * 'libgtop_need_server' - is the server really needed? Defines 'NEED_LIBGTOP'
|
|
dnl if true; defines conditional 'NEED_LIBGTOP'.
