This header and tcl/tk headers are known to conflict. This header |

should be included AFTER tcl.h or tk.h, not before. |

This module defines the fundamental constants used by the rest of |
| 30 |
Ascend and pulls in system headers. There is not a corresponding |
| 31 |
compiler.c. The variables declared in this header are defined |
| 32 |
in ascParse.y. |

* string. Dereferencing a symchar when typedef'd as double will |
| 90 |
* usually cause a bus error unless the string happens to |
| 91 |
