Apparently the Portland group preprocessor refuses to preprocess
input files unless it can also fully parse them as C programs.
This behavior is weird and will break Autoconf-generated scripts.
Try substituting a C preprocessor that is not so all-fired picky:
you can use GCC's preprocessor for that.
