Re: [ft-devel] multithreading and 64 bits

[Tom Kacvinsky]

The long integer type on Windows 64 is 4 bytes wide, not 8 bytes wide.
Thank you, MS!  You will have to use ptrdiff_t if you want a full 8 byte
wide integer type.  Werner, I have not looked at the code recently, but
I assume FT_PtrDist is like ptrdiff_t.
