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