The error messsages suggest that pgcpp is a C++ compiler, not a C
preprocessor.  A quick Google for "pgcpp" would appear to confirm this.

A C preprocessor wouldn't look for identifiers here.

A C preprocessor doesn't expect a ";" anywhere.

The error talks about "compilation", which seems a bit suspicious.

Try something like CPP="pgcc -E" perhaps?
