Log message:
Update to 2.49.2. From the changelog:

## [2.49.2] – 2021-10-16

### Changed

- Lefty is disabled by default in the Autotools build system. To re-enable it,
  pass `--enable-lefty` to `./configure`. In a future release, Lefty will be
  removed.
- remove PHP5 support in SWIG bindings

### Fixed

- Msys experimental packages are included in release artifacts #2130
- CMake build system incorrectly aliases gv2gml to gml2gv #2131
- Gv2gml Doesn't escape quotes in attributes #1276
- GVPR incorrectly understands color schemes #1956

## [2.49.1] – 2021-09-22

### Changed

- the CMake build system installs gzipped man pages if `gzip` is available #1883
- CMake projects using Graphviz as a subproject (`add_subdirectory`) can now
  link against and use `gvc`.

### Fixed

- various problems in the generation of Javascript bindings
- 2.48.0: test suite is failing #2112
- Ensure correct file-level dependency for generated file in cmake generated
  projects #2119

## [2.49.0] – 2021-08-28

### Added

- a very basic C++ API for a subset of the functions in lib/cgraph and
  lib/gvc, allowing a graph to be rendered from DOT source to a
  specified format. The new API is available through two new
  libraries: lib/cgraph++ and lib/gvc++. It is experimental, meaning
  that it might have breaking changes also in upcoming patch or minor
  releases (towards #2001)
- CMake builds now support an `with_expat` option that allows the support for
  using HTML-like labels through the optional expat library to be explicitly
  enabled (default) or disabled
- CMake builds now support an with_zlib option that allows the support for
  raster image compression through the optional zlib library to be explicitly
  enabled (default) or disabled

### Changed

- the CMake build system now enables `-Wextra` when building C++
- some Cgraph functions that take `char*` arguments that they do not modify have
  been updated to take `const char*` arguments #634
- incorrectly using the `layout` attribute on anything other than a graph now
  results in a warning about this being invalid #2078
- `edgepaint` accepts more standard `--` prefixed command line arguments and
  rejects invalid options #1971
- improved detection of Lefty dependencies in the Autotools build system
- libexpr rejects printing the time (`%t`) if no format is provided
- `-DDATE=…` option in the CMake build system has been removed
- the Autotools build system no longer writes the DATE file and the portable
  source tarball no longer includes this

### Fixed

- The attached dot file causes a segfault when processed #2095
- fix typos and update URLs in `edgepaint` usage text and man page
- Fix clang's undefined behavior warning in dotLayout
- gvpr doesn't build on macOS but MKDEFS_EXECUTABLE points to wrong
  directory #2101
- the generated gdefs.h header is no longer installed
- `ccomps` out-of-memory message no longer incorrectly refers to `gc`
- do not abort when `calloc(0, x)` or `calloc(x, 0)` in `gcalloc` return `NULL`
- failed Exshort_t type discrimination #1799
- dot manpage is in wrong directory on Windows #1936
- CMake builds fail when when the ltdl library is not available even if the
  `enable_ltdl` option is `ON`
- CMake builds fail when when the optional `zlib` library is not available
- fix graph rotation in quartz plugin

## [2.48.0] - 2021-07-17

### Added

- a new C++ test infrastructure based on ctest and Catch2 towards #2002

  [lcov](http://ltp.sourceforge.net/coverage/lcov.php) and
  [test coverage visualization in GitLab \ 
MRs](https://docs.gitlab.com/ee/user/project/merge_requests/test_coverage_visualization.html)

### Changed

- updated Graphviz bug report URL in the Autotools build system
- Fix `WIN32` path of `gvc.def` specified in `libgvc_la_LDFLAGS`

  found version is recent enough #1916

### Fixed

- ortho's eqEndSeg incorrectly modifies its arguments #2047
- Autotools enables -Wtrampolines and -Wlogical-op for Clang #2066
- node_distinct_coloring failure due to out-of-memory now reported correctly
  instead of referring to a failure to open lab_gamut
- Fix a typo `GD_LIBS` to `GDLIB_LIBS` in `tclpkg/tcldot/Makefile.am` !2022
- Autotools build system sets libgd variables now instead of incorrectly setting
  GTK variables
- HTML strings used as labels are distinguishable in GXL output by
  `kind="HTML-like string"`
- a Bashism removed from the Autotools build system
- when Criterion is available, the `command_line` test binary is no longer built
  and installed by default, but rather during `make check`
- round-tripping a file through ``gv2gxl`` and then ``gxl2gv`` no longer causes
  HTML-like labels to become non-HTML like labels #517
- fix ODR violation by including the ortho object files in the gvc lib also for
  CMake and MSbuild #2096

various fixes for arm64 big endian support.

most of these simply extend matching from "aarch64" to \ 
"aarch64eb"
in various forms of code.  most remaining uses in pkgsrc of
"MACHINE_ARCH == aarch64" are because of missing aarch64eb support,
such as most of the binary-bootstrap requiring languages like rust,
go, and java.

no pkg-bump because this shouldn't change packages on systems that
could already build all of these.
