(gdb_stdint_h, gdb_stdint.h, stamp-int): Delete. Remove all dependencies on $(gdb_stdint_h). (distclean): Do not delete gdb_stdint.h. * acinclude.m4: Do not use stdint.m4. * configure.ac: Set GNULIB_STDINT_H. Remove tests for stdint.h, uintptr_t, and gdb_stdint.h. * defs.h: Include <stdint.h>. * gdb_thread_db.h: Assume stdint.h is already included. * breakpoint.c, findcmd.c, hppa-tdep.c, inf-ptrace.c, proc-service.c, rs6000-nat.c, spu-linux-nat.c, target.c, win32-nat.c: Do not include gdb_stdint.h. * configure, config.in: Regenerate.
