Update.
1998-05-31 Philip Blundell <philb@gnu.org> * sysdeps/unix/sysv/linux/arm/sysdep.S: Use C_SYMBOL_NAME when referring to errno and _errno. * sysdeps/arm/fpu/feholdexcpt.c: New file. * sysdeps/i386/fpu_control.h: Fix typo. * sysdeps/arm/bits/setjmp.h (__jmp_buf): Remove floating-point support. (_JMPBUF_UNWINDS): Added. * sysdeps/arm/fpu/bits/setjmp.h: New file. 1998-05-25 Gordon Matzigkeit <gord@profitpress.com> * sysdeps/mach/hurd/Makefile: Use the `before-compile' target in order to build header files, not `generated'. * Rules (before-compile): New target which depends on all $(before-compile) files.
