Force dependencies for files which depend on autogenerated headers to ensure that they are always built. * child_info.h (child_info): Add new fields to accommodate new magic number header stuff. * dcrt0.cc: Rely on "child_info_magic.h" to ensure that correct child_info magic numbers are used. (dll_crt0_1): Temporarily remove _cygwin_testing_magic test. (_dll_crt0): Do more testing on magic numbers from fork_info structure. Call "multiple_cygwin_problem" where appropriate. (multiple_cygwin_problem): Rename from multiple_cygwin_die. Issue a warning or die, as appropriate based on cygwin version/magic number mismatch. * pinfo.cc (pinfo::exit): Don't attempt to dereference `this' if it doesn't exist. This can happen when a fatal error occurs early in process initialization. * shared.cc: Rely on "shared_info_magic.h" to accommodate that new magic number header stuff. (shared_info::initialize): Use new magic number stuff, for shared region. (memory_init): Ditto, for mount table. * shared_info.h: Accomodate new magic number stuff for shared region and mount table. * sigproc.cc: Rely on "child_info_magic.h" to accommodate new magic number header stuff. (init_child_info): Initialize new fields in child_info) to accomodate magic numbers. * winsup.h: Rename multiple_cygwin_die to multiple_cygwin_problem. * include/cygwin/version.h: Define macros for manipulating version magic. * cygmagic: New shell script for generating magic numbers.
