No build-shared & build-static failures or binary differences for i686. Mips untested. Andreas, what are some good MIPS cross configurations? [ sysdeps/unix/sysv/linux/llseek.c always passes the two pieces of the 64-bit offset in big-endian order. Is this proper, or should it be conditional on endianness also? ] OK? 2000-07-06 Greg McGary <greg@mcgary.org> * string/endian.h (__LONG_LONG_PAIR): New macro. * sysdeps/unix/sysv/linux/ftruncate64.c: Use it. * sysdeps/unix/sysv/linux/pread.c: Likewise. * sysdeps/unix/sysv/linux/pread64.c: Likewise. * sysdeps/unix/sysv/linux/pwrite.c: Likewise. * sysdeps/unix/sysv/linux/pwrite64.c: Likewise. * sysdeps/unix/sysv/linux/truncate64.c: Likewise. * sysdeps/unix/sysv/linux/mips/ftruncate64.c: Likewise. * sysdeps/unix/sysv/linux/mips/pread.c: Likewise. * sysdeps/unix/sysv/linux/mips/pread64.c: Likewise. * sysdeps/unix/sysv/linux/mips/pwrite.c: Likewise. * sysdeps/unix/sysv/linux/mips/pwrite64.c: Likewise. * sysdeps/unix/sysv/linux/mips/truncate64.c: Likewise.
