33 | /* The libdecnumber library, on which GDB depends, includes a header file |

36 | generates a copy if the system doesn't provide one or if it is missing | |
37 | some features. Unfortunately, gstdint.h and stdint.h cannot be included | |
38 | at the same time, which may happen when we include a file from | |
39 | libdecnumber. | |
