/* Provide forward declarations of core types which are referred to by
|
27 |
|
|
most of the compiler. This allows header files to use these types
|
28 |
|
|
(e.g. in function prototypes) without concern for whether the full
|
29 |
|
|
definitions are visible. Some other declarations that need to be
|
30 |
|
|
universally visible are here, too.
|
31 |
|
|
|
32 |
|
|
In the context of tconfig.h, most of these have special definitions
|
33 |
|
|
which prevent them from being used except in further type
|
34 |
|
|
declarations. This is a kludge; the right thing is to avoid
|
35 |
|
|
including the "tm.h" header set in the context of tconfig.h, but
|
36 |
|
|
we're not there yet. */
