Subject: Make V2.1.60 under gcc 3.3.3 and gcc 3.4.1 fail (Cygwin)

Last week, I've already reported failure of successful
compilation of Octave V2.1.59 on a Cygwin System. See
<http://www.octave.org/mailing-lists/bug-octave/2004/697>.

In that approach, I have used compiler versions
   gcc (GCC) 3.2 20020927 (prerelease)
   g++ (GCC) 3.2 20020927 (prerelease) .


Your replies told me, that gcc version 3.2 might be too old.
So I made a completely NEW installation of Cygwin last week,
updating it to Cygwin Version 1.5.19 ( 2004-Sep-5 Release ).


Here is an excerpt of what '$ cygcheck -s' reports
about my Cygwin setup:

   Windows 2000 Professional Ver 5.0 Build 2195 Service Pack 4
   ...
   MAKE_MODE = `unix'
   ...
   Cygwin DLL version info:
          DLL version: 1.5.11
          DLL epoch: 19
          DLL identifier: cygwin1
          Build date: Sat Sep 4 23:17:09 EDT 2004
   ...

I've installed
          gcc (GCC) 3.3.3 (cygwin special)
          g++ (GCC) 3.3.3 (cygwin special)
even though a newer Compiler version is also vailable
( see below close to end of this message ).


then downloaded latest Octave sources V2.1.60,
and tried to compile it, configured as usual:
'./configure --enable-shared --disable-static'.

Unfortunately '$ make' still stops with the
following message while builing some documentation:

   --- snip ---

   making doc-files
   DOC_FILES = balance.df besselj.df betainc.df ...(long list)...
   toplev.df utils.df variables.df

   making gendoc.cc
   g++ -g -O2 -o gendoc.exe gendoc.cc

   ./gendoc > DOCSTRINGS-t
   mv DOCSTRINGS-t DOCSTRINGS
   make[4]: Leaving directory `/cygdrive/c/.../Octave-2.1.60/src'
   make -C ../../scripts DOCSTRINGS
   make[4]: Entering directory `/cygdrive/c/.../Octave-2.1.60/scripts'
   make[4]: `DOCSTRINGS' is up to date.
   make[4]: Leaving directory `/cygdrive/c/.../Octave-2.1.60/scripts'
   g++ -g -O2 -o munge-texi.exe munge-texi.cc
   making arith.texi from arith.txi
   invalid doc file format
   make[3]: *** [arith.texi] Error 1
   make[3]: Leaving directory `/cygdrive/c/.../Octave-2.1.60/doc/interpreter'
   make[2]: *** [interpreter] Error 2
   make[2]: Leaving directory `/cygdrive/c/.../Octave-2.1.60/doc'
   make[1]: *** [doc] Error 2
   make[1]: Leaving directory `/cygdrive/c/.../Octave-2.1.60'
   make: *** [all] Error 2


At that stage, I got:
$ ls -al src/DOC*
-rw-r--r--    1 Fabian   mkpasswd   234883 Sep 27 09:50 src/DOCSTRINGS

$ ls -al scripts/DOC*
-rw-r--r--    1 Fabian   mkpasswd        0 Sep 27 09:41 scripts/DOCSTRINGS

$ ls -l doc/interpreter/arith.texi*
-rwx------+   1 Administ mkpasswd    31276 Sep 24 20:00 
doc/interpreter/arith.texi
-rw-r--r--    1 Fabian   mkpasswd        0 Sep 27 09:50 
doc/interpreter/arith.texi.t


I'm definitely shure, that 'scripts/DOCSTRINGS' has been
initially a large file containing function 
But why is 'scripts/DOCSTRINGS' now empty at that stage
And why is 'arith.texi.t' created as an empty file ?
What's going on.

==========================================
In addition, I also installed the newer Compiler Version
	gcc (GCC) 3.4.1 (cygming special)
	g++ (GCC) 3.4.1 (cygming special)
and gave it a chance to Compile Octave V2.1.60

I didn't see much difference. GCC 3.4.1 did also
failat the same point ('invalid doc file format')
as GCC 3.3.3 did.

How can I finish compilation ?

Thanks,
Rolf Fabian
