Thanks for reporting this. See attached patch for my preferred fix. The
Crypto++ license allows modifications to the source code, so of course
you're not voiding it by making modifications.
BTW, it's part of the C standard for <stdlib.h> to contain malloc and free.
Why does QNX put them in <malloc.h> instead?
