1998-10-22 Andreas Jaeger <aj@arthur.rhein-neckar.de> * stdio/stdio.h: Use __PMT instead of __P in typedefs. * sysdeps/unix/sysv/linux/mips/bits/sigaction.h: Use __PMT instead of __P for sa_restorer. * sysdeps/unix/sysv/linux/sparc/bits/sigaction.h: Likewise. * sysdeps/unix/sysv/linux/kernel_sigaction.h (struct kernel_sigaction, old_kernel_sigaction): Likewise.
