# Make object files which depend on preprocessor symbols defined in
# the Makefile which are not compilation options but rather configuration
# options dependend on the Makefile. main.c needs MAKE_VERSION while
# shell.c uses DEFSHELLNAME. This will cause recompilation in the case
# the definition is changed in the makefile. It will of course not cause
# recompilation if one does 'make MAKE_SHELL=csh'.

# Directive and keyword tables. We use hash tables. These hash tables have been
# generated with mph (ports/devel/mph)
# If you change the directives or keywords (adding, deleting, reordering) you
# need to create new tables and hash functions (directive_hash, keyword_hash).
#
# The following changes have been made to the generated code:
#
# o prefix the names of the g, T0 and T1 arrays with 'directive_'
# resp. 'keyword_'.
#
# o make the type of the tables 'const [un]signed char' (if you change
# anything make sure that the numbers fit into a char).
#
# o make the hash function use the length for termination,
# not the trailing '\0', via the -l flag in emitc and some editing
# (only for directive_hash).
