[boost] Problems compiling regex with gcc3 on aix and hpux

Hi! I get ugly warnings (they look dangerous to me) when I compile boost/regex on AIX and HP-UX with gcc. On Linux and FreeBSD everything is fine. For example /usr/local/gcc-3.3.3/bin/g++ -c -I. libs/regex/src/cregex.cpp compiles without any complains. On aix43 and hpux11 this gives me the attached warning messages. The order of the messages is slightly different on both platforms, but after sorting the output is identical. I use boost-1.31.0 and see no differences with and without boost-1.31.0-regex-patch-20040503. -- Goetz Isenmann
