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.
