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.

@titlepage
@title Sample Title

@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

@node First Section

First section of first chapter.


@node Second Section
@section Second Section

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?



Have a nice day,
