[boost] Another spirit compile problem using HP aC++

Here's another problem while compiling with aC++. This has been reported to the HP aC++ team, but in the meantime, I'm posting this fix to the list for review and for future users of Spirit for aC++. BTW, I'm a little afraid to commit changes to the repository, so quick question: If I end up committing changes that need to be backed out, can I delete that version that I committed easily? Thanks! boost/spirit/core/primitives/impl/match.ipp:101 ===old=== inline void match<nil_t>::swap(match& other) { std::swap(len, other.len); } ===new=== inline void match<nil_t>::swap(match<nil_t>& other) { std::swap(len, other.len); } -Jerry
