I'm not actually sure how important -fno-exception support is these days. However, assuming this is still desirable (and in any case, it imposes very little overhead compared to the overhead of throwing an exception) the boost_iostreams_no_throw.diff patch replaces all instances of throw foo(); with boost::throw_exception(foo());.

This is *not* sufficient for a clean -fno-exception compile with modern gcc -- we would also need to remove all throw; statements (for rethrowing) and try/catch blocks, although there are very few of them. This patch does not do anything with them.

This patch needs applying after the patch on <https://svn.boost.org/trac/boost/ticket/3612>.

(In [57604]) Use boost::throw_exception. Refs #2094.

Still some throws left when rethrowing caught exceptions.

Thanks to Richard Smith.
