I modified the archive object.c(in C:\ruby\src\ruby-1.8.6\>), I created  
the archive extconfig.rb with the following content:

require “mkmf”  
create\_makefile(“Object”)

and run  
ruby extconfig.rb

“Makefile” was created, and run:

ruby makefile

but, appear this error:

makefile:2: unknown regexp option - h  
makefile:6: syntax error, unexpected ‘.’  
makefile:7: syntax error, unexpected tIDENTIFIER, expecting $end  
topdir = c:/ruby/lib/ruby/1.8/i386-mswin32

What it is happening?

Makefile is for make command.
