I've tried to compile the cryptopp library under QNX 6 but it failed
with the following errors:

It complains that it cannot find the headers file for both the free
and the memcpy function. This is happening in the memcpy_s function.
QNX 6 doesn't have these function available so the
__STDC_WANT_SECURE_LIB__ define equals 0 (or is undefined).
To make the library compile, I've added this two headers in the misc.h
header file:
<code>
#ifdef QNX
// memcpy function and free includes
#include <string.h>
#include <malloc.h>
#endif
</code>
Afterwards, the library compiles successfully. But it is unclear to me
whether there is a better way of doing this... Maybe I am missing a
preprocessor define that would include these? Also does this void the
license if I plan to use it in a commercial product?
Thanks
