Follow-up Comment #2:

Following the Libtool guidelines
<https://www.gnu.org/software/libtool/manual/html_node/C-header-files.html>,
the library header files were corrected to also be usable in C++. The change
has been pushed <https://gitlab.com/makhlaghi/gnuastro/commit/cc89d3c33cc> to
my personal (development) repository. As you see in the Libtool page, this is
much more comprehensive than the suggested addition in the first comment of
this task.

A small test C++ program was also added (in `tests/lib/versioncpp.cpp'). It
will just do the simplest possible job of printing the version number of
Gnuastro, but the important thing is that it is done within C++ which would
fail with the headers before this commit.

I tried temporarily renaming the `g++' executable file to see what would
happen if we don't have a C++ compiler, but apparently Autoconf is too smart
for that and was able to use `gcc' for the C++ compilation. I currently don't
have much experience with C++, but if it is possible to only have a C compiler
(without C++), then it would be great if we could detect that at configure
time and skip this (and possible future) test(s) if the user can't compile
C++.
