Hi,

Looking in stdlib.h, I find:

/* Execute the given line as a shell command.  */
extern int system (__const char *__command) __THROW;

Experimenting with a test program, I found that this error always occurs 
unless <stdlib.h> and <unistd.h> are both included before <vector>.

HOWEVER...my app still won't compile, even after adding  <stdlib.h> and 
<unistd.h> before <vector>. What's going on here?

Sincerely,

Brent
