* sysdeps/unix/sysv/linux/configure.in: New file, start with configure. Add check for installed <linux/version.h> being v2.0 or later. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_open_zero_fill): Call __open instead of open. (_dl_sysdep_fatal): Call __write instead of write. (_dl_sysdep_message): Likewise. Sun Jun 9 20:40:00 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/m68k/fpu/e_acosl.c: New file. * Makerules (o-objects): New variable. Use it in place of $(objects:.o=$o); it filters out $(elide-routines$o). Use o-iterator for ar and ranlib rules so they use the per-type object list. * sysdeps/unix/bsd/ultrix4/sys/mman.h: Likewise.
