>Description:
Bruno Haible did a port of glibc to FreeBSD; in the process he found important differences between glibc and FreeBSD's libc. I looked at some of them to see how they related to POSIX documentation and I found arguments for adopting this changes:

Note about <unistd.h>
- getgrouplist() declaration is moved to <grp.h>.
- initgroups() declaration is moved to <grp.h>.
- setgroups() declaration is moved to <grp.h>.
- mknod() declaration is moved to <sys/stat.h>
Note about <grp.h>:
- setgrent() return type changes from int to void.

Of course the documentation for those 5 functions would also have to change



>How-To-Repeat:
The complete changes are mentioned here:

http://sourceware.org/ml/libc-alpha/2002-10/msg00326.html

but of course things have changed between 2002 and now and some changes, like moving valloc(),in there would break BSD tradition.
