Hi all,

Could anyone tell me if and how I could pass some GCC extra compilation flags 
when building Xen (i.e. make dist-xen)?
I tried:
* when running make: passing EXTRA_CFLAGS
* when running make: passing CFLAGS (this "works" but overrides the rest of the 
* when running ./configure: passing --extra-cflags.
None works.

Is there an established modality for this or must I manually modify the 
The reason I need this is to pass '-save-temps' to GCC, I want to inspect some 
and it would be easier to do that on the preprocessed files.

Thank you,
