[Pedram Ashofteh-Ardakani]

Follow-up Comment #4, task #16288 (project gnuastro):

Nicely done Labib! The message is clear and concise, and the variables and
checks are put in good places. Well done. You should go for the PR :) Mohammad
will also take a look at it before merging to master and setting this task as
complete.

I only have a question about
[https://github.com/labeeb-7z/GnuAstro/commit/91f41f0d6c6c77fac0d2e3664ae1cd9524dd1e86#diff-49473dca262eeab3b4a43002adb08b4db31020d190caaad1594b47f1d5daa810R563-R565
lines 563-565]:


int ver[3]={-1,-1,-1};
wcslib_version(ver);
if(!(ver[0]>=7 && ver[1]>=12))exit(1);


Here, we're declaring `ver` of size 3. Does WCS follow the x.x.x versioning
pattern? Or is it just there to follow some kind of a  standard that the
`wcslib_version` function is following?
