Update.
2003-01-20 Martin Schwidefsky <schwidefsky@de.ibm.com> * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h (INTERNAL_SYSCALL): Fix inline assembler constraints. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h (INTERNAL_SYSCALL): Likewise. * sysdeps/s390/s390-64/Makefile (pic-ccflag): Use -fpic instead of -fPIC.
