* gdb_ptrace.h: New file.
* infptrace.c: Include "gdb_ptrace.h" instead of <ptrace.h> or <sys/ptrace.h>. (PT_READ_I, PT_READ_D, PT_READ_U, PT_WRITE_I, PT_WRITE_D) (PT_WRITE_U, PT_CONTINUE, PT_STEP, PT_KILL): Remove defines. (attach): Don't define PT_ATTACH. (detach): Don't define PT_DETACH. * Makefile.in (gdb_ptrace_h): New variable. (infptrace.o): Update dependencies.
