	prelude.c is an automatically generated file by template/prelude.c.tmpl. However it does not contain any required functions. So remove it from dependency. Also miniprelude.c is included by mini_builtin.c and does not need to make miniprelude.o.

# tool/update-deps verify makefile dependencies.
 | 
						|
 | 
						|
# Requirements:
 | 
						|
#   gcc 4.5 (for -save-temps=obj option)
 | 
						|
#   GNU make (for -p option)
 | 
						|
#
 | 
						|
# Warning: ccache (and similar tools) must be disabled for
 | 
						|
# -save-temps=obj to work properly.
 | 
						|
#
 | 
						|
# Usage:
 | 
						|
#   1. Compile ruby with -save-temps=obj option.
 | 
						|
#      Ex.  ./configure debugflags='-save-temps=obj -g' && make all golf
 | 
						|
#   2. Run tool/update-deps to show dependency problems.
 | 
						|
#      Ex.  ./ruby tool/update-deps
 | 
						|
#   3. Use --fix to fix makefiles.
 | 
						|
#      Ex.  ./ruby tool/update-deps --fix
 | 
						|
#
 | 
						|
# Other usages:
 | 
						|
#   *  Fix makefiles using previously detected dependency problems
 | 
						|
#      Ex.  ruby tool/update-deps --actual-fix [file]
 | 
						|
#      "ruby tool/update-deps --fix" is same as "ruby tool/update-deps | ruby tool/update-deps --actual-fix".
