The most libraries use autoheader, but don't generate such error.
Generation of pg_config.h is ok. The only mistake is include such
autoconf header in headers designed to use with external programs, spi
modules in this case. Autoconf header must be included in source
directly or included in headers for internal use only. And don't be
installed along with other library headers.
