gcc 3.2 complains heavily about keyword mutable not being at the

The attached patch fixes that.

The C++ standard does not enforce mutable placement however since Boost

is already full of compiler specific workarounds I would be happy if this patch could be applied.

May I see a log with the warnings you're getting and the command line you're using?

The warnings: In file included from boost/exception/enable_current_exception.hpp:9, from boost/throw_exception.hpp:40, from boost/regex/v4/regex_workaround.hpp:40, from boost/regex/v4/regex.hpp:32, from boost/regex.hpp:31, from main.cpp:2: boost/exception/exception.hpp:108: warning: `mutable' is not at beginning of declaration In file included from boost/throw_exception.hpp:40, from boost/regex/v4/regex_workaround.hpp:40, from boost/regex/v4/regex.hpp:32, from boost/regex.hpp:31, from main.cpp:2: boost/exception/enable_current_exception.hpp:101: warning: `mutable' is not at beginning of declaration We use compiler switch -W. According to the documentation for -W: Print extra warning messages for these events: ... Storage-class specifiers like "static" are not the first things in a declaration. According to the C Standard, this usage is obsolescent. ... It seems that the warning is also generated in C++ mode although I do not see this requirement in C++98 7.1 (1). gcc 4.1 produces no warning for this code. I cannot turn off -W since this would suppress several other interesting warnings. There seems to be no switch to specifically get rid of this mutable message. Regards, Peter.
