This code quit compiling when I went to XCode 2.0.  What's up with long long?

  typedef unsigned long long PathTrace;

   const PathTrace trace0 = 0;
   const PathTrace trace1 = 0x8000000000000000;

   long long myvar = 0x8000000000000000;

The errors:

/Users/ken/Programs/Cat & Mouse 2view + AI/TestFile.cpp:4: error: integer constant is too large for 'long' type
/Users/ken/Programs/Cat & Mouse 2view + AI/TestFile.cpp:6: error: integer constant is too large for 'long' type

You need to append LL or ULL to the constant (eg 0x8000000000000000ULL)

Thanks, Fred.  That fixed it right up.

Now, where was this NEW REQUIREMENT documented?  I read the 2.0 release notes carefully, and found nothing of the sort.

gcc 4.0 is trying to be more conformant to the C/C++ spec, which IIRC says that constants fit into the smallest of s/u char, short or int that will fit by default. long long is not in the standard.

Cheers, Glen Low
