/* Provide forward declarations of core types which are referred to by |
|
|
26 |
most of the compiler. This allows header files to use these types |
|
|
27 |
(e.g. in function prototypes) without concern for whether the full |
|
|
28 |
definitions are visible. Some other declarations that need to be |
|
|
29 |
universally visible are here, too. |
|
|
30 |
|
|
|
31 |
In the context of tconfig.h, most of these have special definitions |
|
|
32 |
which prevent them from being used except in further type |
|
|
33 |
declarations. This is a kludge; the right thing is to avoid |
|
|
34 |
including the "tm.h" header set in the context of tconfig.h, but |
|
|
35 |
we're not there yet. */ |
