16 First, it determines the size of off_t and time_t variables, and generates
17 macro code to define OFF_T_FMT and TIME_T_FMT as suitable formats, if they are
18 not already defined in the system-specific header file.
20 Then it reads Makefile, looking for certain OS-specific definitions which it
21 uses to define some specific macros. Finally, it reads the defaults file
24 The defaults file contains normal C #define statements for various macros; if
25 the name of a macro is found in the environment, the environment value replaces
26 the default. If the default #define does not contain any value, then that macro
