[BZ #140]
2004-04-29 Philip Blundell <pb@nexus.co.uk> * sysdeps/arm/dl-machine.h (RTLD_START): Avoid unnecessary GOT entries. [BZ #140] * sysdeps/unix/sysv/linux/sys/sysctl.h: Remove linux/compiler.h include. (_LINUX_KERNEL_H, _LINUX_TYPES_H, _LINUX_LIST_H): Only define if not yet defined, #undef back after including linux/sysctl.h if defined here. (__LINUX_COMPILER_H, __user): Define if not yet defined, #undef back after including linux/sysctl.h if defined here.
