Re: Octave chokes on this in some systems

[Shai Ayal]

Just to add to the general confusion it runs well on my NOT vanilla (shall 
we say chocolate?) FC4 with octave 2.1.71 where all octave stuff is 
compiled using gcc-3.2.3:

`mkoctfile -p CXX` -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man 
--infodir=/usr/share/info --enable-shared --enable-threads=posix 
--disable-checking --with-system-zlib --enable-__cxa_atexit 
--enable-languages=c,c++,f77 --disable-libgcj --host=i386-redhat-linux
Thread model: posix
gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-47.fc4)
