Reported by Howard Chu . * sysdeps/generic/glob.c: Also protect FNM_* macros from being undefined in a second inclusion. 1998-06-20 Mark Kettenis * sysdeps/mach/hurd/i386/Makefile: New file. * sysdeps/mach/hurd/i386/init-first.c [!PIC] (init1): Call __libc_init_secure. (_hurd_stack_setup): Renamed from __libc_init_first. (__libc_init_first): New function. * sysdeps/mach/hurd/i386/static-start.S: New file. 1998-05-30 Mark Kettenis * sysdeps/mach/hurd/i386/init-first.c 1998-06-22 Andreas Schwab * grp/initgroups.c: Use _CALL_DL_FCT. 1998-06-23 Mark Kettenis * elf/dl-load.c (_dl_map_object_from_fd): Add missing cast. --- sysdeps/mach/hurd/i386/Makefile | 7 +++++++ sysdeps/mach/hurd/i386/init-first.c | 21 ++++++++++++++++----- sysdeps/mach/hurd/i386/static-start.S | 28 ++++++++++++++++++++++++++++ 3 files changed, 51 insertions(+), 5 deletions(-) create mode 100644 sysdeps/mach/hurd/i386/Makefile create mode 100644 sysdeps/mach/hurd/i386/static-start.S (limited to 'sysdeps') diff --git a/sysdeps/mach/hurd/i386/Makefile b/sysdeps/mach/hurd/i386/Makefile new file mode 100644 index 0000000..49f609c --- /dev/null +++ b/sysdeps/mach/hurd/i386/Makefile @@ -0,0 +1,7 @@ +ifeq ($(subdir),csu) +extra-objs += crt0.o +install-lib += crt0.o + +$(objpfx)crt0.o: $(objpfx)static-start.o $(objpfx)abi-note.o $(objpfx)init.o + $(link-relocatable) +endif diff --git a/sysdeps/mach/hurd/i386/init-first.c b/sysdeps/mach/hurd/i386/init-first.c index 10094f0..07718d3 100644 --- a/sysdeps/mach/hurd/i386/init-first.c +++ b/sysdeps/mach/hurd/i386/init-first.c @@ -1,5 +1,5 @@ /* Initialization code run first thing by the ELF startup code.
