From 194d9eb318403b1618c3f77eba6de4e17b7c900d Mon Sep 17 00:00:00 2001 From: Corinna Vinschen Date: Mon, 12 May 2003 11:06:27 +0000 Subject: [PATCH] * Makefile.in (CYGWIN_START): Define as crt0.o. Add to TARGET_LIBS. * fhandler.h (fhandler_virtual::fstat): Remove useless declaration. * fhandler_virtual.cc: Remove _COMPILING_NEWLIB define. * ipc.cc (ftok): Use stat64. * syscalls.cc (_fstat64): Remove alias. (_fstat): Ditto. (_stat): Ditto. (_fstat64_r): New function. (_fstat_r): Ditto. (_stat64_r): Ditto. (stat_r): Ditto. * crt0.o: New file, moved from newlib. * include/sys/param.h: Ditto. * include/sys/utime.h: Ditto. * include/sys/utmp.h: Ditto. * include/sys/dirent.h: Ditto.
