The following is the email copied from [email protected]. The

compiler error is same in our case. Maybe this compiler error can be

ignored here since it is not related to the redundancy patch.

Ok, we think that the Pentium compiler may have an internally defined

macro called 'varArgs', which is the name of the variable at the error

location. Please try this patch (the diff is against the original

R3.14.9 file), which instead renames that group of variables:
