Janne Blomqvist ea99ec5bd6 PR 78534, 83704 Handle large formatted I/O ... In order to handle large characters when doing formatted I/O, use size_t and ptrdiff_t for lengths. Compared to the previous patch, based on discussions on IRC use size_t for sizes that don't need to be negative rather than ptrdiff_t everywhere. Regtested on x86_64-pc-linux-gnu, approved as part of the PR 78534 approval, committed to trunk. libgfortran/ChangeLog: 2018-01-07 Janne Blomqvist <jb@gcc.gnu.org> PR fortran/78534 PR fortran/83704 * io/fbuf.c (fbuf_init): Use size_t instead of int for length.
