* bootstrap.conf: Use c_strtod, so that even in French locales "1.5"
is accepted, instead of "1,5".
* src/counterexample.c, src/state-item.c: Use xtime_t instead of
time_t, so that accuracy goes from seconds to nanoseconds.
( counterexample_init): Depend on cex.timeout rather than
$TIME_LIMIT.
* doc/bison.texi (%define Summary): Document cex.timeout.
It is not available on HP-UX 11i.

Gnulib provides no replacement, but anyway we should be using doubles,
since difftime uses doubles.
* bootstrap.conf: We want portability on stdtod.
* src/counterexample.c: Use double, not float, for time measurements.
Use of print_unicode_char suggested by Bruno Haible.

* src/gram.h (print_dot_fallback, print_dot): New.
* src/gram.c, src/derivation.c: Use it.
* tests/counterexample.at, tests/report.at: Adjust the test suite.
* .travis.yml, README-hacking.md: Adjust.

* bootstrap.conf: We need fstrcmp.
* src/symtab.c (symbol_from_uniqstr_fuzzy): New.
(complain_symbol_undeclared): Use it.
* tests/diagnostics.at (Suggestions): New.
* data/bison-default.css (insertion): Rename as...
(fixit-insert): this, as this is what GCC uses.
* bootstrap.conf: We need winsz-ioctl and winsz-termios.
* src/location.c (columns): Use winsize to get the number of
columns.
Code taken from the GNU Coreutils.
* src/location.h, src/location.c (caret_init): New.
* src/complain.c (complain_init): Call it.
* tests/bison.in: Export COLUMNS so that users of tests/bison can
enjoy proper line truncation.
So far diagnostics were cheating: in addition to the 'column' field of
locations (based on actual screen width per multibyte characters and
on tabulation expansion), the scanner sets the 'byte' field.
Diagnostics used this byte count to decide where to insert (color)
style.
We want to be able to truncate the quoted lines when there are too
wide to fit the screen. This requires that the diagnostics learn how
to count columns, the byte-in-boundary trick no longer works.
Bytes are still used for fix-its.
* bootstrap.conf: We need mbfile for mbf_getc.
* src/location.c (caret_info): We need an mbfile.
(caret_set_file): Initialize it.
(caret_getc): Convert to mbfile.
(location_caret): Instead of relying on the byte position to decide
where to insert the color style, count the current column using
boundary_compute.
We were using the gnulib's gettext module with tricks in
bootstrap.conf to avoid useless files. Instead, use gnulib's
gettext-h module.
* .travis.yml: Force Gettext 0.18.3 on Trusty.
* bootstrap.conf: Use gettext-h instead of gettext.
(excluded_files): Remove.
* configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.19.
Bruno Haible just added a default implementation of libtextstyle's
interface when the library is not available.
https://lists.gnu.org/archive/html/bison-patches/2019-03/msg00025.html
* gnulib: Update.
* bootstrap.conf: Replace libtextstyle with libtextstyle-optional.
* src/complain.c, src/getargs.c: Remove now useless cpp guards.
The timevar and bitset modules now use the c99 module which causes
$CXX to now include -std=gnu++11 when possible. Unfortunately, G++
4.7 does not implement [[noreturn]] in C++11 mode, so our tests of
glr.cc (which uses _Noreturn) fail with
input.cc:954:1: error: expected unqualified-id before '[' token
right before [[noreturn]]. 4.8 works fine.
* data/skeletons/c.m4 (b4_attribute_define): Do not use [[noreturn]]
with GCC 4.7.

This is very easy to do, thanks to work by Bruno Haible in gnulib.
See "Supporting Relocation" in gnulib's documentation.
* bootstrap.conf: We need relocatable-prog and relocatable-script (for yacc).
* src/yacc.in: New.
* configure.ac, src/local.mk: Instantiate it.
* src/main.c, src/output.c (main, pkgdatadir): Use relocatable2.
* doc/bison.texi (FAQ): Document it.
* README-hacking: Commit before bootstrapping.
* bootstrap.conf: gnulib_mk is no longer defined by bootstrap.
* bootstrap, gnulib, lib/.gitignore, m4/.gitignore: Update/regen.
