* src/input/vfscanf.cxx (vfscanf): Silence warning. * include/stdio.h: Add file operation functions which weren't here before! While I'm here, add __THROW everywhere and use __externC not externC. * cdl/stdio.cdl: We implement stdio fileops in isoinfra now. Also set header for that. Build fileops.cxx. L_tmpnam must be at least 4. TMP_MAX must be at least 1, and ISO C says it should be >=25. Add description for CYGPKG_LIBC_STDIO_FILEIO and move up from bottom so it goes with others. * src/common/fileops.cxx: New file. Implements rename(), remove(), tmpnam() and tmpfile(). * src/common/fclose.cxx: Add throw specifiers to match stdio.h. * src/common/feof.cxx: Ditto. * src/common/fflush.cxx: Ditto. * src/common/fopen.cxx: Ditto. * src/common/freopen.cxx: Ditto. * src/common/fseek.cxx: Ditto. * src/common/setvbuf.cxx: Ditto. * src/common/snprintf.cxx: Ditto. * src/common/sprintf.cxx: Ditto. * src/common/sscanf.cxx: Ditto. * src/common/stdioinlines.cxx: Ditto. * src/common/ungetc.cxx: Ditto. * src/common/vsnprintf.cxx: Ditto. * src/common/vsscanf.cxx: Ditto. * src/input/fgetc.cxx: Ditto. * src/input/fgets.cxx: Ditto. * src/input/fread.cxx: Ditto. * src/input/fscanf.cxx: Ditto. * src/input/gets.cxx: Ditto. * src/input/scanf.cxx: Ditto. * src/input/vfscanf.cxx: Ditto. * src/output/fnprintf.cxx: Ditto. * src/output/fprintf.cxx: Ditto. * src/output/fputc.cxx: Ditto. * src/output/fputs.cxx: Ditto. * src/output/fwrite.cxx: Ditto. * src/output/printf.cxx: Ditto. * src/output/vfnprintf.cxx: Ditto.
