Ok, I get your point about the impossibility to merge some of dietlibc into libpayload.
But for purpose of using tinyscheme as a scripting language on top of coreboot, would the fact the interpreter's executable is linked against GPL code also make any scheme script using it necessarily GPL ?
In the patches I sent you, the dietlibc part is kept separate from libpayload. In any case, I'll see if I can remove the dietlibc dependency, I had actually started to implement some of the missing functions before I found out about dietlibc.

Thank you very much for your efforts.

Please note that libpayload is _not_ released under the GPL, but under
the BSD license (just like tinyscheme, btw), so it can not share code
with GPL projects.
Please also check http://www.coreboot.org/Development_Guidelines#How_to_contribute,
especially the section on signing off patches. :-)
