* configure.in (AC_CHECK_HEADERS): Check for sys/procfs.h.
Also check for gregset_t and fpregset_t types. * configure: Regenerate. * core-regset.c (sys/procfs.h): Only include if HAVE_SYS_PROCFS_H is defined. (fetch_core_registers): Turn into stub unless both HAVE_GREGSET_T and HAVE_FPREGSET_T are defined. These changes allow systems like linux that are migrating to /proc support to use a single configuration for both new and old versions. * config/i386/linux.mt: Note that this is now for both a.out and ELF systems. * config/i386/linux.mh (NATDEPFILES): Add solib.o, core-regset.o, i386v4-nat.o * config/i386/tm-linux.h (tm-sysv4.h): Include. * config/i386/xm-linux.h (solib.h): Include (SVR4_SHARED_LIBS): Define. * i386v4-nat.c: Only compile if HAVE_SYS_PROCFS_H is defined. (supply_gregset, fill_gregset): Compile if HAVE_GREGSET_T defined. (supply_fpregset, fill_fpregset): Compile if HAVE_FPREGSET_T defined.
