[PATCH] Another warning fix in adaint.c

[Jakub Jelinek]

Hi!

Following patch fixes another warning in adaint.c:
../../gcc/ada/adaint.c: In function 'void __gnat_killprocesstree(int, int)':
../../gcc/ada/adaint.c:3284:26: warning: suggest parentheses around assignment 
used as truth value [-Wparentheses]
   while (d = readdir (dir))
                          ^

Bootstrapped/regtested on x86_64-linux, ok for trunk?

        * adaint.c (__gnat_killprocesstree): Avoid -Wparentheses warning.
