Hello, All!

I write simple code: =============mpl_enum.cpp============= #include #include #include <iostream>

enum test_e {ONE, TWO, THREE};

void f(test_e e) { const char* names[] = {"ONE", "TWO", "THREE"}; std::cout<

typedef boost::mpl::range_c< test_e, ONE, static_cast(THREE + 1)

...

range;

int main() { boost::mpl::for_each<range>(f); return 0; }

[snip more errors] Hmm, looks like a bug to me. Fixed in the CVS main trunk (the diffs are attached, in case you would like to fix it locally - currently it takes up to 24 hours for anonymous CVS servers to reflect the changes). Thanks for the report! Aleksey
