This is some outdated book which is in need of an update. :-)

The easiest solution (for my library) was to create a second
configuration header file containing only what is needed to use the
library.  This is a tiny subset of the defines required to actually
build the library.  The second configuration header is manually
maintained.  The configuration headers may be configured like

  AC_CONFIG_HEADERS([build_config.h api_config.h])

so build_config.h.in is automatically maintained by autoheader, while
api_config.h.in is manually maintained by copying desired entries from
build_config.h.in.

Library users would include api_config.h, but the library
implementation includes build_config.h.
