1998-08-24 Martin Baulig <martin@home-of-linux.org> * *.c (glibtop_init_p): Using correct `(1 << GLIBTOP_SYSDPES_*)'. * cpu.c, mem.c: Removed `const' from sysctl () constants to keep compiler happy. * procmem.c: Added missing call to `glibtop_init_p'. * prockernel.c: Casting `nwchan' to `unsigned long' since this normally has the same size than a pointer. Well, is there a FreeBSD for 64bit architectures ?
