>Description:
Doing parallel byte operations with and's, or's fails to run correctly when using --fugly-logint.

The file below is good example of how a.and.b works differently from and(a,b)

Please compile example with g77 -fugly-logint
>How-To-Repeat:
Just compile file with -fugly-logint and run to see difference between 2 outputs.
>Fix:
I have no idea, except that .and. should behave as and(.,.) in my opinion. But I am no expert.
