c.opt: Add -W(no-)overlength-strings.
gcc: * c.opt: Add -W(no-)overlength-strings. * doc/invoke.texi: Document it. * c-opts.c (c_common_handle_option): -pedantic implies -Woverlength-strings, if not explicitly disabled already. (c_common_post_options): -Woverlength-strings defaults to off, and is always off for C++. * c-common.c (fix_string_type): Issue warning about strings longer than is portable only if warn_overlength_strings. Rearrange code a little for clarity. * configure.in: Check for -Wno-overlength-strings as well before enabling -pedantic in stage 1. * Makefile.in (STRICT2_WARN): Add -Wno-overlength-strings. (gcc.o-warn, insn-automata.o-warn, build/gencondmd.o-warn): Delete. * genconditions.c (write_header, write_one_condition) (write_conditions, write_writer): Consolidate very long strings that were broken up to fit in C89 portable limit. Don't use printf when fputs will do. gcc/testsuite: * gcc.dg/Woverlength-strings.c * gcc.dg/Woverlength-strings-pedantic-c89.c * gcc.dg/Woverlength-strings-pedantic-c89-no.c * gcc.dg/Woverlength-strings-pedantic-c99.c * gcc.dg/Woverlength-strings-pedantic-c99-no.c: New tests. ================================================================== From-SVN: r110360
