This is going to be very useful, thanks Doug. From the regression
reports (http://tinyurl.com/2uvxrz), I see this version of GCC is not
happy at all with xpressive. There are at least two problems:
In file included from ../boost/detail/atomic_count.hpp:97,
../boost/detail/atomic_count_gcc.hpp:20:28: error: bits/atomicity.h: No
such file or directory
This could be that the test machine is misconfigured, or that
atomic_count.hpp needs a patch for this version of GCC.
The other problem is:
../boost/xpressive/detail/core/state.hpp:95: error: declaration of
'typedef struct boost::xpressive::detail::match_context<BidiIter>
../boost/xpressive/detail/core/state.hpp:33: error: changes meaning of
'match_context' from 'struct
The code it's complaining about looks like:
typedef BidiIter iterator;
typedef core_access<BidiIter> access;
typedef match_context<BidiIter> match_context;
It seems this version of GCC doesn't like my typedef'ing of
match_context<It> to match_context. I think this is a compiler bug.
Where should I report this bug?
