bug#69717: Warnings about prototype mismatch from makeinfo

[Tomas Volf]

Hello,

when I take an example .texi file from Texinfo's manual:



\input texinfo
@settitle Sample Manual 1.0

@copying
This is a short example of a complete Texinfo file.

@end copying

@titlepage
@title Sample Title

@contents

@node Top
@top GNU Sample

This manual is for GNU Sample

@menu
* First Chapter::    The first chapter is the
                      only chapter in this sample.
* Index::            Complete index.
@end menu


@node First Chapter
@chapter First Chapter

@cindex chapter, first
This is the first chapter.
@cindex index entry, another

Here is a numbered list.

@enumerate

This is the first item.

This is the second item.
@end enumerate



@node First Section
@section First Section

First section of first chapter.


@node Second Section
@section Second Section

Second section of first chapter.


@node Index
@unnumbered Index

@printindex cp

@bye



And try to produce .info file from it, I get several warning about subroutines
being redefined with mismatching prototypes:

Am I doing something wrong or is this expected?
