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

31# Directive and keyword tables. We use hash tables. These hash tables have been
32# generated with mph (ports/devel/mph)
33# If you change the directives or keywords (adding, deleting, reordering) you
34# need to create new tables and hash functions (directive_hash, keyword_hash).
35#
36# The following changes have been made to the generated code:
37#
38#	o prefix the names of the g, T0 and T1 arrays with 'directive_'
39#	  resp. 'keyword_'.
40#
41#	o make the type of the tables 'const [un]signed char' (if you change
42#	  anything make sure that the numbers fit into a char).
43#
44#	o make the hash function use the length for termination,
45#	  not the trailing '\0', via the -l flag in emitc and some editing
46#	  (only for directive_hash).
