This will be safe only if your compiler is using the exact same GCC 
version that is used for GCC-XML's parser (GCC 3.3).  The C++ ABI is not 
stable across compiler versions.  If you still want to proceed you may 
be able to get things working.

The gccxml/GCC/gcc/config directory has a bunch of headers that 
configure the compiler's host and target architectures.  Look in 
gccxml/GCC/config_cmake for how the architecture is chosen.  You'll have 
to mess a bit with this code to select the target architecture used when 
building gccxml_cc1plus.
