15 | /* This auxiliary program builds the file config.h by the following | |
16 | process: | |
17 | ||
c6c2dc1d PH |
18 | First, it determines the size of off_t and time_t variables, and generates |
19 | macro code to define OFF_T_FMT and TIME_T_FMT as suitable formats, if they are | |
20 | not already defined in the system-specific header file. | |
b1c749bb PH |
21 | |
22 | Then it reads Makefile, looking for certain OS-specific definitions which it | |
23 | uses to define some specific macros. Finally, it reads the defaults file | |
24 | config.h.defaults. | |
059ec3d9 PH |
25 | |
26 | The defaults file contains normal C #define statements for various macros; if | |
27 | the name of a macro is found in the environment, the environment value replaces | |
28 | the default. If the default #define does not contain any value, then that macro | |
29 | is not copied to the created file unless there is some value in the | |
30 | environment. | |
31 | ||
32 | This program is compiled and run as part of the Make process and is not | |
33 | normally called independently. */ | |
