This looks promising.

I am trying to write unit tested parsing code for a cgi module. 
Different parsing routines need to be run in different situations; the
only reliable way to check whether MOD_RUBY is in use is to do if
defined? MOD_RUBY or if MOD_RUBY.

I have to be able to turn the constant on and off, b/c I have to test
other parsing situations as well.
