# Autoreconf uses a perl script to inline includes from Makefile.am into
# Makefile.in before ./configure is ever run even once ... which typically means
# AX_AUTOMAKE_MACROS forfeit access to substitutions or conditional logic
# because they enter the picture after those steps. We're intentially using the
# expanded value of @INC_AMINCLUDE@ directly so the include will be inlined. To
# bootstrap we must pre-seed an empty file to avoid a 'file not found' error on
# first run. Subsequently running ./configure will generate the correct content
# based on the configuration flags and also get re-inline into Makefile.in.
