One this kind of system:
2.4.21-192-default #1 Wed Feb 18 19:26:28 UTC 2004 i686 i686 i386 GNU/Linux

the code found on this page:
http://www.research.att.com/~bs/3rd_code.html,

at this bullet:
Chapter 22:  pg 668 Slices and matrix example (sec22.4.5,224.6,22.6.2),

and located at this URL: 
http://www.research.att.com/~bs/matrix.c,

fails to build with a simple g++ matrix.c  on the command line.  

I have tried this with both GCC 3.3.2 (which succeeds) and GCC 3.4.0 (which 
fails).  In both cases I built GCC with these configure options:
 "--prefix=/opt/org/gnu/gcc-3.4.0 --enable-languages=c++,c".

Both builds were done in a fresh build directory using make bootstrap. The 
relevant environment variables such as LIBRARY_PATH, CPLUS_INCLUDE_PATH, PATH 
are all set by one GNU_GCC variable which I changed for each build. 

Could someone please verify this.

Here's the carnage:
