Description:
------------
If you are building on windows and run configure.js with --help one of 
the options you get is 

 --enable-crt-debug            Extra CRT debugging

I discovered that meant if an error ocurred in PHP you got a large 
memory dump (or dump of some kind) printed to stderr. I propose the help 
message be changed to something more helpful such as:

 --enable-crt-debug            Extra CRT debugging (this produces LARGE 
memory dumps to stderr)

If enable-crt-debug does more than that a note indicating this will 
produce output most people would find prohibitively verbose should be 
noted.
