How widely supported is variable type 'long long int' ?

Many thanks to all who responded. Your comments have been
very useful.

For those who wondered why I needed long longs:
My app makes extensive use of unsigned long bitmaps and bitwise
logic. Enhancements to the app occasionally require defining new
bit positions and in some cases I'm getting close to running out.
It would be far simpler to switch to unsigned long long than to
reprogram to use multiple unsigned longs.

It might be even simpler to switch once to an array of unsigned char
and never have to worry about type sizes again.

Thanks for the suggestion. However just the thought of all the
recoding that would require makes my brain hurt
