PR 78534, 83704 Large character lengths
This patch fixes various parts of the code to use a larger type than int for the character length. Depending on the situation, HOST_WIDE_INT, size_t, or gfc_charlen_t is appropriate. Regtested on x86_64-pc-linux-gnu and i686-pc-linux-gnu. gcc/fortran/ChangeLog: 2018-01-22 Janne Blomqvist <jb@gcc.gnu.org> PR 78534 PR 83704 * arith.c (gfc_arith_concat): Use size_t for string length.
