It looks like pgcc is trying to enforce C++ keyword restrictions ("operator"
and "class" are reserved words in C++ but not in C.) Can you see if there
is some flag to send to the compiler to have it use just ANSI C as the input
language?

[I might be wrong here, since I don't have the Portland group compiler. Is
it possible that you are on an OS (e.g. Windows) that does not preserve case
in file names? (pgCC is a C++ compiler, pgcc should be a C compiler.)]

It might be worth trying to set CC=gcc in your config.h; but this is even
more of a stretch than what is suggested above.

...good luck...dac
