The Ada program didn't check for sucessful file opens,
and didn't check for Storage_Error, so I did the same
in my C code.

Your program has a leak. The C version necessarily
differs from the Ada version in that it must allocate
memory on the heap, so the returned pointer must be
freed by the caller.

Instead,
     while (1)
     {
         _1st_line = first_line_of_file(TEST_FILE);
         fputs(_1st_line, stdout);
         free(_1st_line);
     }

Unnecessary in C code, provided you include the correct
header file. Realloc returns a void*, which in C converts
to any other pointer without a cast.
