GCC 3.2

[Kevin B. Hendricks]

Hi,

Atttached is a datatest.cxx file I abstracted from code that does this in 
the cppu module of OpenOffice.org.  I am not the original author of the 
code (I just pulled it into a standalone version to ease testing).  The 
code is LGPL'd so it should be fine for inclusion if you want it.

Under gcc 2.95.X compile with 
g++ -O2 -odatatest datatest.cxx
./datatest

Under gcc 3.X compile with
g++ -DADJUST_ALIGN -O2 -odatatest datatest.cxx
./datatest

It was not meant to necessarily show problems.  It was meant to detect 
changes from gcc 2.95.X to gcc 3.X that would impact OpenOffice.org C++ to 
UNO component bridging code.

Hope this helps,

Kevin
