Hello

Here are some problems (with partial fixes) I encountered as I was
trying to install Octave version 2.1.31 on a 2xR12000 Octane running
IRIX 6.5.4m. egcs-2.91.66 and gmake 3.78.1 were used. Installation
commands were (bash):

 export CC=egcs
 export CFLAGS=-O2              # no fear
 export CXX=egcs
 export CXXFLAGS=-O2
 export LIBS=-lstdc++
 ./configure --prefix=$HOME
 gmake
 gmake install

* src/oct-time.cc:
 The macro definitions at the top of oct-time.cc conflict with system
header files, resulting in a undefined struct timeval:

#if !defined (_BSD_SOURCE)
#define _BSD_SOURCE 1
#define OCTAVE_UNDEFINE_BSD_SOURCE
#endif

#if !defined (_XOPEN_SOURCE)
#define _XOPEN_SOURCE 1
#define OCTAVE_UNDEFINE_XOPEN_SOURCE
#endif

On my machine, simply commenting out these lines fixes the problem. I
suggest during the configuration step a little bit of code could be
compiled, in order to determine wether _BSD_SOURCE and _XOPEN_SOURCE
have to be manually defined (this is not the case on IRIX systems).

* doc/interpreter/Makefile.in:
 - $(LIBS) is missing in `munge-texi' compilation line (-lstdc++ is
needed)
 - ` at anchor' tags only appear in Texinfo 4.0 . Texinfo version should be
checked during configuration step to prevent users like me from getting
an incomplete info documentation installed ;-) (I had Texinfo 3.12
installed)

* Makeconf.in:
 `texi2dvi' is defined as:
   TEXI2DVI = $(top_srcdir)/texi2dvi
 this is a problem when top_srcdir was set to `.' in the root directory
and used as-is in subdirs.


Thanks for this neat software!

Jeremy
