Use (void) in no-arguments function definitions
- From: "Joseph S. Myers" <joseph at codesourcery dot com>
- To: <libc-alpha at sourceware dot org>

- Subject: Use (void) in no-arguments function definitions
This patch converts no-arguments function definitions to use (void) to
specify a prototype where they previously used empty parentheses.
(This is logically part of the goal of using prototype function
definitions everywhere and enabling -Wold-style-definition, but this
case seems a bit separate from the case where the old-style
definitions specify function parameters.)
Tested x86_64; the only differences in disassembly of glibc's .so
files are, as for the "register" patch, changed address offsets.
