Details

Description:
Since version 8.3, if compiled with `extra/source-highlight`, gdb supports fancy syntax highlighting in its TUI source view.

Excerpt from the NEWS file:
* Terminal styling is now available for the CLI and the TUI. GNU
Source Highlight can additionally be used to provide styling of
source code snippets. See the "set style" commands, below, for more
information.


gdb manually compiled after installing source-highlight:
https://ibb.co/KmKFNpv

and it's linked with highlighting lib:
```
kk@kk /tmp/gdb-8.3/gdb $ ldd ./gdb | grep high
libsource-highlight.so.4 => /usr/lib/libsource-highlight.so.4 (0x00007fb755e1e000)
kk@kk /tmp/gdb-8.3/gdb $
```

Packaged Arch's gdb – no highlighting:
https://ibb.co/5rpDqNh

and no linkage:
```
kk@kk /tmp/gdb-8.3/gdb $ ldd `which gdb` | grep high
kk@kk /tmp/gdb-8.3/gdb ✘ $
```


Additional info:
* package version(s)
gdb-8.3-1
* config and/or log files etc.
-
* link to upstream bug report, if any

Steps to reproduce:
- gdb ./app
- b main
- r
- <C-x>, <a>

I want this feature too. It`s not a hard job.

Attaching a patch for the current PKGBUILD. The generated package works on my machine but i'm not sure if the patch makes source-highlight a hard dependency or an optional one.

That would make it a hard dependency it seems. gdb with source-highlight uninstalled:
gdb: error while loading shared libraries: libsource-highlight.so.4: cannot open shared object file: No such file or directory
even if I have 'set style sources off' in .gdbinit. Still, I think it's worth it.
