| // Compiler check: |
| // |
| // Historically, Spirit supported a lot of compilers, including (to some |
| // extent) poorly conforming compilers such as VC6. Spirit v1.6.x will be |
| // the last release that will support older poorly conforming compilers. |
| // Starting from Spirit v1.8.0, ill conforming compilers will not be |
| // supported. If you are still using one of these older compilers, you can |
| // still use Spirit v1.6.x. |
| // |
| // The reason why Spirit v1.6.x worked on old non-conforming compilers is |
| // that the authors laboriously took the trouble of searching for |
| // workarounds to make these compilers happy. The process takes a lot of |
| // time and energy, especially when one encounters the dreaded ICE or |
| // "Internal Compiler Error". Sometimes searching for a single workaround |
| // takes days or even weeks. Sometimes, there are no known workarounds. This |
| // stifles progress a lot. And, as the library gets more progressive and |
| // takes on more advanced C++ techniques, the difficulty is escalated to |
| // even new heights. |
| // |
| // Spirit v1.6.x will still be supported. Maintenance and bug fixes will |
| // still be applied. There will still be active development for the back- |
| // porting of new features introduced in Spirit v1.8.0 (and Spirit 1.9.0) |
| // to lesser able compilers; hopefully, fueled by contributions from the |
| // community. For instance, there is already a working AST tree back-port |
| // for VC6 and VC7 by Peder Holt. |
| // |
| // If you got here somehow, your compiler is known to be poorly conforming |
| // WRT ANSI/ISO C++ standard. Library implementers get a bad reputation when |
| // someone attempts to compile the code on a non-conforming compiler. She'll |
| // be confronted with tons of compiler errors when she tries to compile the |
| // library. Such errors will somehow make less informed users conclude that |
| // the code is poorly written. It's better for the user to see a message |
| // "sorry, this code has not been ported to your compiler yet", than to see |
| // pages and pages of compiler error messages. |
