Inheriting CFLAGS

[Jerome Brown <guruswami@orcon.net.nz>]

I am attempting to install Xen-2.0 using the Gentoo Ebuilds written by 
Philip Taylor, and have run into the same problem as A Streecar Named 
with needing to implement the -nopie flag.

As part of the Portage system, Gentoo users are able to specify their 
CFLAGS in a file which is exported to the environment in which the 
program is configured, built and installed.

Is it possible to have Xen inherit these CFLAGS as a base, and then 
modify them as required? Part of the enthusiasm over Gentoo is the 
ability to customise and optimise the applications.

Thanks in advance

Jerome
