I tested with gcc 3.4 on ubuntu intrepid and 'make check' all passed.   
I suspect the problem is related to the data type macros in <liblas/ 
cstdint.hpp> and poor interactions with BSD.

define them as variables on your configure line (note the switch for  
the spatial indexing and OCI stuff is svn trunk only at this point):

CC="/usr/bin/gcc-3.4" CXX="/usr/bin/gcc-3.4" ./configure        --with- 
gdal=/usr/bin/gdal-config \
		--with-oci=yes \
                 --with-spatialindex=/usr/local \
                 --with-geotiff=/usr \
                 --enable-debug

Hope this helps,

Howard
