10 | # --------------------------------------- | ||
11 | # Find the absolute name of a header file, assuming the header exists. | ||
12 | # If the header were sys/inttypes.h, this macro would define | ||
13 | # ABSOLUTE_SYS_INTTYPES_H to the `""' quoted absolute name of sys/inttypes.h | ||
14 | # in config.h | ||
15 | # (e.g. `#define ABSOLUTE_SYS_INTTYPES_H "///usr/include/sys/inttypes.h"'). | ||
16 | # The three "///" are to pacify Sun C 5.8, which otherwise would say | ||
17 | # "warning: #include of /usr/include/... may be non-portable". | ||
18 | # Use `""', not `<>', so that the /// cannot be confused with a C99 comment. | ||
