Comment(by Richard Smith <richard@…>):

 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>.
