Update.
* libio/fileops.c (_IO_new_file_open): Recognize ,ccs= in mode string and load appropriate conversions. * libio/iofwide.c (__libio_codecvt): Renamed from libio_codecvt and made global. * libio/libioP.h: Declare __libio_codecvt. * manual/stdio.texi: Document ,ccs= option for fopen. * wcsmbs/wcsmbsload.c (__wcsmbs_named_conv): New function. * wcsmbs/wcsmbsload.h (__wcsmbs_named_conv): Declare. * libio/iofclose.c: Free conversion data if stream was wide-oriented. * sysdeps/unix/sysv/linux/i386/Dist: Add sys/io.h.
