Meh -- that code has gone 18+ years before breaking.

R also defines WARNING in its headers. If I remember correctly there are (or at 
least were, it *has* been 18+ years since I looked at this particular thing) 
some odd differences in the R headers under Windows and Linux.

In any case we would be happy to use "PGERROR".

Would an equivalent "PGWARNING" be something we are open to adding and 
back-patching?
