| 15 | // Compiler check: |
|---|
| 16 | // |
|---|
| 17 | // Historically, Spirit supported a lot of compilers, including (to some |
|---|
| 18 | // extent) poorly conforming compilers such as VC6. Spirit v1.6.x will be |
|---|
| 19 | // the last release that will support older poorly conforming compilers. |
|---|
| 20 | // Starting from Spirit v1.8.0, ill conforming compilers will not be |
|---|
| 21 | // supported. If you are still using one of these older compilers, you can |
|---|
| 22 | // still use Spirit v1.6.x. |
|---|
| 23 | // |
|---|
| 24 | // The reason why Spirit v1.6.x worked on old non-conforming compilers is |
|---|
| 25 | // that the authors laboriously took the trouble of searching for |
|---|
| 26 | // workarounds to make these compilers happy. The process takes a lot of |
|---|
| 27 | // time and energy, especially when one encounters the dreaded ICE or |
|---|
| 28 | // "Internal Compiler Error". Sometimes searching for a single workaround |
|---|
| 29 | // takes days or even weeks. Sometimes, there are no known workarounds. This |
|---|
| 30 | // stifles progress a lot. And, as the library gets more progressive and |
|---|
| 31 | // takes on more advanced C++ techniques, the difficulty is escalated to |
|---|
| 32 | // even new heights. |
|---|
| 33 | // |
|---|
| 34 | // Spirit v1.6.x will still be supported. Maintenance and bug fixes will |
|---|
| 35 | // still be applied. There will still be active development for the back- |
|---|
| 36 | // porting of new features introduced in Spirit v1.8.0 (and Spirit 1.9.0) |
|---|
| 37 | // to lesser able compilers; hopefully, fueled by contributions from the |
|---|
| 38 | // community. For instance, there is already a working AST tree back-port |
|---|
| 39 | // for VC6 and VC7 by Peder Holt. |
|---|
| 40 | // |
|---|
| 41 | // If you got here somehow, your compiler is known to be poorly conforming |
|---|
| 42 | // WRT ANSI/ISO C++ standard. Library implementers get a bad reputation when |
|---|
| 43 | // someone attempts to compile the code on a non-conforming compiler. She'll |
|---|
| 44 | // be confronted with tons of compiler errors when she tries to compile the |
|---|
| 45 | // library. Such errors will somehow make less informed users conclude that |
|---|
| 46 | // the code is poorly written. It's better for the user to see a message |
|---|
| 47 | // "sorry, this code has not been ported to your compiler yet", than to see |
|---|
| 48 | // pages and pages of compiler error messages. |
