3441	boost::pool cast alignment warnings on Sparc	Evan Jones <evanj@…>	Chris Newbold	"This may not be fixable, but I generally have been compiling my code on Sparc using GCC's -Wcast-align to catch places where code may attempt to make an unaligned access. When I use boost::object_pool, I get the compiler warnings below. I don't know of any ""clean"" way to avoid this. I've added a pragma to pool.hpp to suppress the warning when this file is included.

System: Solaris 10, Sparc (where alignment matters)
Compiler: GCC 4.4.0
Boost: Boost 1.40.0
Command line: gcc -Wcast-align -c objpooltest.cc -Iboost_1_40_0
