Description of problem:

Hello there,

I just tried to compile package bdflush-1.5-21 from Redhat 8.0.

Here are some of the compiler messages.

bdflush.c:74: warning: operation on `ptr' may be undefined
bdflush.c:79: warning: operation on `ptr' may be undefined

Here is a patch which fixes the messages.
