Well if your compiler purports to be an ANSI compiler and supports some
other operator presednce then it is broken and you should complain
to the vendor.  Do you want to claim that because some compilers are
broken you can't write ansi complient code?

I'll admit that vendors tend to vary in how they handle "undefined"
behaviour and yes you will run into problems if you get in the habit
of passing null pointers to strcmp etc. because the DEC compiler let you.
