        * libc/include/stdio.h (FILE): define __SCLE for "convert line
        endings" for Cygwin.
        (__sgetc): convert line endings if needed
        (__sputc): ditto
        * libc/stdio/fdopen.c (_fdopen_r): Remember if we opened in text mode
        * libc/stdio/fopen.c (_fopen_r): ditto
        * libc/stdio/freopen.c (freopen): ditto
        * libc/stdio/fread.c (fread): perform CRLF conversions if __SCLE
        * libc/stdio/fvwrite.c (__sfvwrite): ditto
