Edit: I was wrong what I posted before. stdio.h is on my system:
$ ls -l /usr/include
...
-rw-r--r-- 1 root root 2799 Mar 3 20:38 stdio_ext.h
-rw-r--r-- 1 root root 29665 Mar 3 20:38 stdio.h
so installing another package won’t help this. You need to either correct the path in whatever you are using or get you money back.
