[Boost-users] regex: match_results::const_reference is sometimes sub_match<Bidi Iterator>, sometimes const char?

Hello, all. The regex library is extremely helpful: thanks for all your efforts. I've got a problem with gcc and stlport and boost: when I try to get a submatch on other platforms, I can take my match object, m, and do things like m[n].str(); // works great elsewhere But with gcc / stlport, with BOOST_NO_STD_ALLOCATOR not defined, the const_reference type is defined as Allocator::const_reference (which is `const char'), rather than sub_match<BidiIterator>. So operator[] gives me a char, and life isn't so good. Any hints as to where I went astray? Richard
