Operating Systems Solaris How do I compile a 64-bit program on SPARC?? Post 302274236 by otheus on Wednesday 7th of January 2009 05:05:24 AM

Again, The problem with casting signed int into unsigned int is that this discards the "sign" bit (it's a tad bit more complicated than that). For some reason, size_t appears to be signed, and therefore can be negative. You cannot convert a negative number of any size into a bigger integer that is non-negative. (It can be done, but you risk "losing information"). So either ignore the warning, or make size_t unsigned, or make DWORD signed.
