Update.
* po/sv.po: Update from translation team. * sysdeps/unix/sysv/linux/sparc/sparc32/syscalls.list: Add __vfork as alias. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise. 1999-01-24 Andreas Jaeger <aj@arthur.rhein-neckar.de> * ctype/ctype.h (toupper,tolower): Use __inline instead of inline, define inline functions only when optimizing for speed and __USE_EXTERN_INLINES is set. 1999-01-24 Ulrich Drepper <drepper@cygnus.com> * ctype/ctype.c (toupper): Correct variable names from last change.
