# Form the builtin file
#
# We ave a "chicken-and-egg" problem.  We want the builtn help file to
# accurately reflect the function list.  It would be nice if we could
# just execute calc show builtin, but calc may not have been built or
# buildable at this point.  The hack-a-round used is to convert ../func.c
# into a standalone program that generates a suitable function list
# that is standwiched between the top and bottom builtin help text.
#
# We form funclist.c by sedding out unwanted stuff from builtins table,
# converting NUMBER* and VALUE into harmless types and converting
# the showbuiltins() function into main().  Combined with the -DFUNCLIST
# we will avoid all of the complex calc types, macros and defines and
# be left with just main() and a mininal builtins table.
#
# Building funclist.o a portable fashion is ugly because some systems
# do not treat -I.. correctly!
