38/* The libdecnumber library, on which GDB depends, includes a header file
39 called gstdint.h instead of relying directly on stdint.h. GDB, on the
40 other hand, includes stdint.h directly, relying on the fact that gnulib
41 generates a copy if the system doesn't provide one or if it is missing
42 some features. Unfortunately, gstdint.h and stdint.h cannot be included
43 at the same time, which may happen when we include a file from
44 libdecnumber.
45
46 The following macro definition effectively prevents the inclusion of
47 gstdint.h, as all the definitions it provides are guarded against
