Update.
2003-09-27 Wolfram Gloger <wg@malloc.de> * malloc/malloc.c: Include <malloc-machine.h> earlier instead of "thread-m.h", so that default parameters can be overridden in a system-specific malloc-machine.h. Remove extra ; from extern "C" closing brace. * sysdeps/generic/malloc-machine.h: New file. * sysdeps/mach/hurd/malloc-machine.h: New file. * malloc/thread-m.h: Removed. * malloc/Makefile: Remove CFLAGS-malloc.c parameter addition, it is in sysdeps/generic/malloc-machine.h now. * elf/dl-reloc.c (_dl_allocate_static_tls): Move definition of variables only used if TLS_TCB_AT_TP is defined into the #if branch.
