There is another solution to this. The problem arises because MSL headers
(like <cstring>) include Apple's libc headers when targeting Mach-O, and the
libc headers are not wrapped inside a 'namespace std'. So I put the
following in my prefix file:

namespace std
{
using ::memset;
using ::memchr;
using ::memcmp;
using ::memcpy ;
using ::memmove;
using ::strlen;
using ::strcpy;
using ::strncpy;
using ::strcat ;
using ::strncat;
using ::strcmp ;
using ::strncmp;
using ::strcoll;
using ::strxfrm;
using ::strchr ;
using ::strrchr;
using ::strpbrk;
using ::strspn ;
using ::strcspn;
using ::strtok ;
using ::strstr;
using ::strerror;
// etc.
}

Then I can reference std::XXX wherever I want, either directly or with a
using std::XXX.

I chose this approach because I expect the MSL problem will go away quite
soon (I haven't checked CW8 yet, but I heard that they were going back to
using their own libc implementation) and I don't want to mess up my sources
unnecessarily. In particular, I don't want to put 'using' declarations in my
header files when I have methods that take arguments with std:: types or
have inline methods that use std:: functions. MSL correctly implements
Standard C++ for CFM-Carbon, so I prefer to keep my sources compatible with
the standard.
