Shouldn't you have

#  undef foreach

after

#  pragma push_macro("foreach")

?

As for GCC, we're still testing 4.4 (http://tinyurl.com/no2q5wh ). Besides,
there are other compilers outside the three big ones, so I'm not so
convinced about this patch.

I think it's fair to declare Boost.Foreach unusable in the presence of
"foreach" macros, and we should only strive to be resilient against
these for libs that do not depend on Boost.Fo… €¡…́¥ÌÑ¡”…Í”)™½È	½½Íй5ձѥ%¹‘•à°Ý¡¥ µ•É•±ä•¹ÍÕɕ́¥¹Ñ•É½Á•É…‰¥±¥ÑäÝ¥Ñ ¥Ð¤¸)M¼™…È°‘¥É•ÐÕÍ”½˜‰½½ÍÑ}™½É•…¡}…ɝյ•¹Ñ}‘•Á•¹‘•¹Ñ}±½½­ÕÁ}¡…¬Í••µÌ)µ½É”É½‰ÕÍи())½…Å×µ¸43ÍÁ•è5׎è)Q•±•›͹¥„
