Update.
* sysdeps/ieee754/dbl-64/e_pow.c (log1): Define and initialize two52 locally. (log2): Likewise. * sysdeps/ieee754/dbl-64/upow.h: Remove definition of two52. Patch by Simon Gee <simong@agile.tv>. * sysdeps/unix/sysv/linux/getsysstats.c (__get_nprocs_conf): Prefer reading /proc/stat since it is more uniform across architectures.1 * manual/texinfo.tex: Update to latest official version.
