- To use this file, make up a file with a name like:
-
- ?????svr3.h
-
- where ????? is replaced by the name of the basic hardware that you
- are targeting for. Then, in the file ?????svr3.h, put something
- like:
-
- #include "?????.h"
- #include "svr3.h"
-
- followed by any really system-specific defines (or overrides of
- defines) which you find that you need. For example, CPP_PREDEFINES
- is defined here with only the defined -Dunix and -DSVR3. You should
- probably override that in your target-specific ?????svr3.h file
- with a set of defines that includes these, but also contains an
- appropriate define for the type of hardware that you are targeting.
