Warnings about prototype mismatch from makeinfo

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.

Copyright @copyright{} 2016 Free Software Foundation, Inc.

@end copying

@titlepage

@title Sample Title

@page

@vskip 0pt plus 1filll

@insertcopying

@end titlepage

@contents

@node Top

@top GNU Sample

This manual is for GNU Sample

@menu

only chapter in this sample.

@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

@item

This is the first item.

@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:

/tmp $ guix shell -C gcc-toolchain texinfo -- makeinfo xxx.texi

Am I doing something wrong or is this expected?

Have a nice day,
