Included gypi values overwrite including gypi file's #400

What steps will reproduce the problem?
1. create a gypi file fileA setting a variable named "a" to "a" in a variables 
dict
2. create a gypi file fileB setting value variable "a" to "b"
3. in fileB import fileA
4 running gyp with -IfileB one would expect the variable "a" to resolve to the 
value "b" but it does not.  It is the value "a"

What is the expected output? What do you see instead?
One would expect that the included is parsed first, then the including is 
parsed, thereby becoming the last writer.

In LoadOneBuildFile
https://code.google.com/p/gyp/source/browse/trunk/pylib/gyp/input.py#233
Upon cursory inspection, it appears that the opposite is the case, the file is 
parsed, then the includes are merged on top.

What version of the product are you using? On what operating system?
