FreeBSD port (38): avoid warnings in linuxthreads

[Bruno Haible]

When building with --enable-all-warnings, I get these warnings:

errno.c:24: warning: function declaration isn't a prototype
errno.c:37: warning: function declaration isn't a prototype

This fixes it.


linuxthreads/ChangeLog:
2002-09-04  Bruno Haible  <bruno@clisp.org>

	* errno.c (__errno_location, __h_errno_location, __res_state): Use
	prototype function declaration.
