[Gcl-devel] gcl-2.6.6 installation creates invalid info/dir file

[Bruno Haible]

Hi,

When gcl install its documentation, it does so with commands that append
a few lines to INFO_DIR/dir. The problem is: If the dir file does not yet
exist - this is frequent because gcl is one of the first packages to install
into $prefix/share/info rather than the traditional $prefix/info - then
the created file contains just this:

==============================================================================
* GCL Doc: (gcl-si.info).       GNU Common Lisp specific Documentation.
* GCL TK Doc: (gcl-tk.info).    TK window GCL interface.
* GCL Ansi Doc: (gcl.info).  Ansi Common Lisp Specification.
==============================================================================

and is invalid because
  . It lacks the "* Menu:" label
  . It lacks the node separator and the node header that should follow.

Suggestion: Use 'install-info' to install the info files, if it is present;
otherwise if no dir file exists, don't create one.

'install-info' is part of the texinfo package since 1996.
