* dcrt0.cc (child_info_fork::handle_fork): Call _pei386_runtime_relocator here. (dll_crt0_1): Ditto for non-fork case. * dll_init.cc (dll::init): Complain more in comment. Clean up slightly. (dll_dllcrt0_1): Call _pei386_runtime_relocator when we know we have a filled-in per_process structure. * globals.cc (__cygwin_user_data): Accommodate new fields for _pei386_runtime_relocator. * pseudo-reloc.cc: New file adapted from old lib/pseudo-reloc.c. Include winsup.h directly. Collapse #ifdef __CYGWIN__ into one block. Perform minor whitespace code reformatting. (__report_error): Use small_printf to output error. (_pei386_runtime_relocator): Conditionalize for cygwin to take per_process pointer parameter. * winsup.h (_pei386_runtime_relocator): Declare. * include/cygwin/version.h (CYGWIN_VERSION_PER_PROCESS_API_VERSION_COMBINED): New macro. (CYGWIN_VERSION_USER_API_VERSION_COMBINED): Use above macro. (CYGWIN_VERSION_USE_PSEUDO_RELOC_IN_DLL): New macro. (CYGWIN_VERSION_API_MINOR): Bump to 227. * include/sys/cygwin.h: Remove obsolete comment. (per_process::unused2): Shorten. (per_process::pseudo_reloc_start): New field. (per_process::pseudo_reloc_end): Ditto. (per_process::image_base): Ditto. * lib/_cygwin_crt0_common.cc: Declare pseudo runtime externs needed for per_process structure. (_cygwin_crt0_common): Fill in pseudo_reloc runtime constants. * lib/pseudo-reloc-dummy.c: New file. Dummy function to satisify ld. * lib/pseudo-reloc.c: Delete.
