24 | * General portability note: |
---|
25 | * MSVC mis-compiles explicit function template instantiations. |
---|
26 | * For example, f<A>() and f<B>() are both compiled to call f<A>(). |
---|
27 | * BCC is unable to implicitly convert a "const char *" to a std::string |
---|
28 | * when using explicit function template instantiations. |
---|
29 | * |
---|
30 | * Therefore, avoid explicit function template instantiations. |
